Description

200937390 六、發明說明： ， 【發明所屬之技術領域] 本發明係’-種諸如雙層類型勵及CD(C卿如msc) 之多層類型資訊記錄媒體、一種諸如DVD記錄器之記錄裝置 及-種用於將資訊記錄於資訊記錄媒體上之方法，及一種上 面記錄有電腦程式之電腦可讀取記錄媒Μ，該電腦程式使得 電腦充當此記錄裝置。 【先前技術】 在此類型記錄裝置中’試圖通用化藉由記錄裝置執行記錄 所在之_貝sfU己錄媒體。舉例而言，作為資訊記錄媒體之一實 例，在資訊記錄媒體中，諸如在CD—R〇M(c〇mpact Disc—200937390 VI. Description of the Invention: [Technical Field] The present invention is a multi-layer type information recording medium such as a double-layer type excitation and a CD (C Qing such as msc), a recording device such as a DVD recorder, and A method for recording information on an information recording medium, and a computer readable recording medium on which a computer program is recorded, the computer program causing the computer to function as the recording device. [Prior Art] In this type of recording apparatus, it is attempted to generalize the recording medium in which the recording is performed by the recording apparatus. For example, as an example of an information recording medium, in an information recording medium, such as CD-R〇M (c〇mpact Disc-

Only Memory)、CD-R(C〇mpact Disc-Recordable)、DVD-ROM、 DVD-R、DVD-RW(DVD-Recordable Disc)、及 DVD+R 中，已開 發多層類型或雙層類型之資訊記錄媒體（諸如，光學碟片）， 其中複數個記錄層被層壓或黏結於同一基板上，如在日本專 利申請案特許公開案第2006-019019號中所揭示。此外，在 於此雙層類型（亦即，兩層類型）光學碟片上執行記錄之記錄 裝置（諸如，DVD記錄器）上，記錄雷射束聚焦於自雷射束照 射侧來觀察是位於前部（亦即，在較接近於光學讀寫頭之側 上）的記錄層（在本申請案中，在有必要時，在下文中稱為 “L0”層）上，以藉此藉由熱以可重寫方法及不可逆變化記 錄方法將資訊記錄至L0層中。此外，雷射束通過L0層而聚 097146734 200937390 焦於自f射束照射彳絲觀察是位於後部（亦即，在較遠離於 光子讀寫碩之側上）的記錄層（在本申請案中’在有必要時， -在下文中稱為“Ll ）上，以藉此藉由熱以可重寫方法及 . 不可逆變化記錄方法而將資訊記錄至L1層中。 舉例而δ ’日本專利申請案特許公開案第2006-019019 5虎揭不一種技術’該技術對將記錄使用者資料之一區域之至 少一部分進行預先寫入，以使得當在L1層中執行記錄時， ©雷射束在該雷射束明確地透射通過L()層中之記錄區域的同 時聚焦於L1層上，以確保u層中之最内部圓周及最外部圓 周上的記錄效能。 在此雙層類型光學碟片中，若將資料記錄至L1層中，則 有必要使雷射束照射通過L0層。在此狀況下，在雷射束透 射通過之L0層中’在一些狀況下記錄資料，且在其他狀況 下不記錄資料。若如上所述並未整合L0層之記錄狀態，則 ® 照射於L1層上之雷射束之光量改變，此係因為透射通過L0 層的光之透射率視是否對L0層進行記錄而改變。因此，界 定一所謂之記錄次序，其中藉由預先使L0層處於所記錄狀 . 態而將L0層中之透射率設定為恆定的，且將資料適當地記 . 錄至L1層中。 此處，當在L1層中之資料區域之内部圓周側及外部圓周 側上的邊緣部分中執行記錄時，使自透鏡照射之雷射束以圓 錐形狀聚焦於L1層上。在L0層中’雷射束亦透射通過超出 097146734 5 200937390 L1層中之資料區域之邊緣部分的較遠内部圓周側或較遠外 部圓周侧上之區域。若包括如上所描述之内部圓周側或外部 圓周側的L0層中之幾乎整個被透射區域並未處於記錄狀 態’則照射於L1層上之雷射束之光量會受到影響，此係因 為存在透射通過L0層之光量的變化。 因此，舉例而言，在雙層且寫入一次類型之記錄媒體（例 如，雙層類型DVD-R)或其類似者中，L1層中之資料區域具 有比L0層中之資料區域之結構窄一預定量的結構。該預定 量在雙層類型DVD-R之標準中被判定為藉由使間隙長声與 容限長度相加而獲得之值，其中間隙長度為在焦點位於U 層上時雷射束透射通過的L0層中之圓形區域之半徑與^ 層與L1層之間的偏心率之容差之和，且容限長度為界^、 L0層中之位址及界定於L0層中之位址中之每一者自預^ 置的位置移位之容差。因此，依據標準，L1層中夕咨^ 心貢料區 域被設定為在兩個邊緣中比L0層中之資料區域窄間隙長片 與容限長度的和。結果，L1層中之資料區域之記錄办β 螺41被 界定為相對小於L0層中之資料區域的記錄容量。 然而’在具有此資料區域之雙層類型DVD-R的狀況下，^ 層中之資料區域容量可能小於資料凹坑（data pi1〇列藉& 每一記錄層中之印模（stampa)形成的雙層且唯讀類型之# 體（例如，雙層類型DVD-ROM)之資料區域的記錄容量。因 此’舉例而言，在針對雙層類型DVD-ROM配置之資料被j己錄 097146734 6 200937390 至雙層類型_4上的狀況下，存在在所有資料中之待記錄 至11層中之資料量超出雙層類型_-R之L1層中的資料區 -域容量之情況下幾乎不可能記錄所有資料的問題。 •—更具體而言’雙層類型國一_ ^LO層及L1層中的記錄 令量最大占為4.27GB。另一方面，雙層類型DVD_R之記錄 谷量通常為在L0層中之4.2863GB及在L1層中之 4. 2597GB。因此，關於呈待記錄至雙層類型DVD_R〇M上之格 ®式之内容資料’若待記錄於L1層中之資料的大小超出 4. 2597GB ’則無法按原樣記錄資料，此係因為無法將資料置 放於雙層類型DVD_R2L1層中。 另一方面’若記錄於雙層類型DVD_R〇MiL1層中之資料 區域中的内容資料為4.2597 GB或更小，則可認為可將内容 資料按原樣記錄至雙層類型DVD_R上。然而，在雙層類型 @ DVD-R中，記錄於u層中之資料區域之大小被設定為小於 記錄於L0層中之資料區域的大小。因此，若記錄至u層中 之内容資料之大小與記錄至L0層中之内容資料的大小實質 上彼此相等’則存在無法按原樣記錄内容資料之問題。 • 在雙層類型DVD-β中，如圖10(a)中所示，為了遵守記錄 - 次序，L1層中之資料區域之最外部圓周位址χ(豎線）的位置 通常自L0層中之資料區域之最外部圓周位址X的位置朝向 内部圓周侧移位一對應於如上所描述的間隙長度與容限長 度之和之長度。此外，L1層中之資料區域之内部圓周侧上 097146734 7 200937390 的邊緣部分通常---⑺丫之㈣區域之内部固田 部分朝向外部圓周侧移位對餘如上所描述 容限長度之和的長度。 門隱長度與 因此’關於L0層中之位址與u層中之 位置關係遍及整個碟片表面為不對準的。：： 碟片之最外部圓周之内部側執行層跳躍所針對之内容，若記 錄於L0射之資料的結束位址為γ，則記錄於li層中之資 料的起始位址為Y(豎線）。亦即，L1層中之記料始位置二 終在L0層中之記錄結束位置的内部圓周側上，且u層中之 記錄結束位置始終在L 0層中之記錄起始位置的外部圓周側 上。因此，即使記錄於雙層類型DVD-ROM之L1層中之資料 區域中的内容資料為4. 2597 GB或更小，仍可能存在以下技 術問題：在將記錄於雙層類型DVD-R0M(其具有記錄於L〇層 與L1層中之内容資料之大小實質上相等的特性）上之内容 資料按原樣記錄至雙層類型D V D - R上的情況下，資料無法記 錄於L1層中之資料區域内。具體而言，如圖1〇(^)中所示， 例如，若記錄至L0層及L1層中之每一者中的3.0 GB大小 之内谷 > 料被按原樣記錄至DVD-DL上，貝彳待記錄至li層中 之内容資料無法置放於L1層中的資料區域中，且將進入引 出區域。 【發明内容】 鑒於則述習知問題’因此本發明之一目的為提供一種記錄 097146734 8 200937390 裝置及方法，一種上面記錄有電腦程式之電腦可讀取記錄媒

層；及一第二記錄層，該第一記錄層包括一其中藉由照射雷 097146734 11 200937390 射束而讀内容資料之第一資料區域，該第二記錄層包括一 其中藉由通過第一記錄層照射雷射束而記錄内容資料之第 一貝料區域’該記錄裝置具備：-記錄器件，其用於藉由照 射雷射束而將内容資料記錄至第一資料區域及第二資料區 域中’一第―讀取器件’其用於讀取指示第-資料區域及第 了資料區域中之每一者的記錄容量之容量資訊；-第二讀取 器件其讀取包括於内容資料巾或附加至内容資料且係 用以管理内容資叙+达 ^ ^ 欠 貧抖之管理資訊；一劃分器件，其用於根據容 量貝訊及&理資訊’將内容資料劃分為待記錄至第一資料區 域中之第 > 料及待記錄至第二資料區域中之第二資料；及 控制器件，其用於控制記錄器件以將第一資料記錄至第一 資料區域中且將第二資料記錄至第二資料區域中。 根據本發明之記錄裝置之具體例，當將内容資料記錄至包 括第一記錄層及第二記錄層之記錄媒體上時，將内容資料劃 分為第一資料及第二資料，且分別將第一資料及第二資料記 錄至第一資料區域及第二資料區域中。此時，若分別將第一 資料及第二資料記錄至第一資料區域及第二資料區域之一 部分中（亦即，若第一資料及第二資料中之每一者的資料大 小小於第一資料區域及第二資料區域各自的大小），則記錄 器件受到控制’使得第一資料及第二資料中之每一者被相鄰 地記錄至第一資料區域及弟'一資料區域各自的最内部圓周 (亦即，與内部圓周側接觸地記錄）’且第一資料及第二資料 097146734 12 200937390 中之每一者被記錄至記錄媒體上。此外，在第一資料及第二 資料之外部圓周側處，記錄中間區域資料直至最外部圓周為 . 止。 . 此處，待記錄於記錄媒體上之内容資料通常（例如）如在下 載銷售中一般係經由網路（諸如，網際網路）分散；然而，内 容資料可如在衛星數位廣播及陸上數位電視廣播中一般以 數位方法被廣播。此外，内容資料可具有用於在分散或廣播 ❹ 階段記錄至記錄媒體上之碟片影像資料的格式。 關於内容資料被劃分為第一資料及第二資料且每一資料 被記錄至不同記錄層中之資料區域中的記錄媒體，存在（例 如）雙層類型DVD-R0M(DVD-R0M雙層）及雙層類型DVD-R。此 處，已知存在兩個記錄媒體之區域結構上的差異。 在雙層類型DVD-ROM中，第一記錄層（L0層）及第二記錄 層（L1層）中之每一者具有相同的資料區域之容量。另一方 ® 面，在雙層類型DVD-R中，鑒於間隙長度與容限長度，L1 層中之資料區域之容量被設定為小於L0層中之資料區域的 容量。結果，雙層類型DVD-R之L1層中之資料區域的容量 - 小於雙層類型DVD-ROM之L1層中之資料區域的容量。 . 因此，例如，為了將雙層類型DVD-ROM之内容資料記錄至 雙層類型DVD-R上，有必要改變雙層類型DVD-R之區域結 構，或在記錄過程中將内容適當地分至L0層及L1層中。 然而，在具體例中，首先借助於第一讀取器件，讀取容量 097146734 13 200937390 資訊’該容量資訊指示第-資料區域及第二資料區域之記錚 容量。同時，借助於第二讀取器件，讀取用以管理:容= 之管理資訊。此處，舉例而言，管理資訊可為指示猶後描述 之添加至内容之齡點之候選位置的資訊’或可為對於記錄' 裝置自身制劃分點之候選位置為必要的資訊。該點係為了 - 將雙層類型DVD-職之内容資料記錄至具有不同於雙層類 型DVD-ROM之區域結構的區域結構之雙層類型Dm，用 以將内容資料適當地劃分為第—資料及第二資料之任何冑 訊在具體例中包括於“管理資訊，，之範圍内。此外，關於對 於記錄裝置自身偵測劃分點之候選位置為必要的資訊，例 如，列出諸如視訊管理器資訊（Vide〇 Manager Inf〇rmati〇n， VMGI)及視訊標題集資訊（Vide〇 Title如祕職⑽， VTSI)之IFO檔案（資訊檔案）作為一實例。更具體而言，例 如，在IF0檔案中，為單元之邊界（該單元為内容資料之再 生單位），亦為錯誤校正碼（Err〇r c〇rrecti〇n c〇de，ec〇 ❹ 區塊之邊界（該區塊為資料記錄單位）且並不藉由無縫回放 旗標（seamless playback nag)(其指示是否確保連續再生） 確保之位置被偵測為劃分點之候選位置^劃分點之候選位置 藉由劃分叙操作來偵測。此時，藉由執行錢㈣之程 序’甚至並非為ECC邊界之位置亦可添加至劃分點之候選位 置。 接著，右在以上描述之劃分候選點處劃分内容資料，則劃 097146734 14 200937390 分ι§件在容量資訊之基礎上判斷所產生之第一資料及第二 資料是否可分別記錄至第一資料區域及第二資 料區域中。此 * 處’若劃分點並非為ECC邊界，則如稍後詳述，緊於檔案系 統之後°己錄—扇區單位之虛設資料，使得L0層中之資料之 ^端與ECC邊界匹配。接著，實際上以被判斷為可記錄之劃 刀H點作為劃分點來劃分内容資料，且分別將所劃分之内 I資料（亦即’第一資料及第二資料）記錄至第一資料區域及 〇 第一>料區域中。 此時，對於為（例如）視訊資料之内容資料而言，有可能偵 測到劃分點之位置。此外，當在所彳貞測之劃分點處執行劃分 時，内容資料可藉由判斷是否具有一允許記錄於記錄媒體之 每=貝料區域中的大小而被適當地劃分。結果，有可能在不 改變雙層類型DVD_R之區域結構之情況下較佳地記錄雙層 類i聽職的内容資料。亦即，有可能在不改變記錄媒體 之區域結構的情況下回應於各種内容資料有效地記錄内容 資料。 在本發明之記錄裝置之具體例之一態樣中，控制器件將對 * 應於第二資料區域的最大容量之位置之位址自初始狀態移 * 位至較遠内部圓周側，使得第二資料區域之記錄容量被擴展 直至至少一預定容量。 根據此態樣’鑒於間隙長度及容限長度而被設定為窄於第 資料區域（亦即’ L〇層中之資料區域）之第二資料區域（亦 097146734 15 200937390 即，L1層中的資料區域）被擴展至與第二資料區域之最内部 圓周相比定位於較内部的引出區域中），且連同前述操作， 第二資料區域之記錄容量增加一預定大小。此處，舉例而 言’第二資料區域可被擴展’使得第二資料區域之容量實質 上等於雙層且唯讀類型之媒體（例如，雙層類型DVD-ROM)之 L1層中之資料區域的記錄容量。此外，“初始狀態”指示 預先判定之“第二資料區域”中之區域結構的狀態，且通 常，其指示雙層且寫入一次類型之記錄媒體（例如，雙層 DVD-R)之區域結構的狀態。 此時’具體例中之記錄媒體之第二資料區域之容量變為等 於雙層類型DVD-ROM的第二記錄層之容量。結果，有可能將 雙層類型DVD-ROM之資料記錄至雙層類型DVD_R上。 此外，在此態樣中，控制器件可控制記錄器件以最遲在記 錄第一資料之刖將預資料記錄至與第一資料區 域：起始位置的内部圓周侧相鄰之至少一預定區域中。 ^助於此構造’藉由預先將預資料記錄於第-記錄層中之

此時，具體例中之記錄媒體之第二資料區域之容量變為等 於雙層類型DVD-ROM的第二記錄層之容量。結果，有可能將 雙層類型DVD-ROM之資料記錄至雙層類型DVD-R上。 此外，在此態樣中，在擴展第二資料區域的同時，將第一 資料區域擴展與第二資料區域之擴展量相同的量。此時，第 一資料區域與第二資料區域之間的由間隙長度及容限長度 引起之大小差並未改變，記錄次序得以保持，且可執行至第 二資料區域中之適當記錄。 在本發明之記錄裝置之具體例的另一態樣中，劃分器件根 據管理資訊，偵測内容資料之至少一劃分點候選者的位置， 且在劃分點候選者處劃分内容資料，（i)在該劃分點候選者 處，内容資料之起始位置與劃分點候選者之間的大小與一為 用於控制内容資料之再生之資訊的檔案系統之大小的和係 等於或小於第一資料區域的最大容量，且（ii)在該劃分點候

(C〇mpact Disc-Recordable), DVD-ROM, DVD-R, DVD-RW (DVD-Recordable Disc), and DVD+R A recording medium (such as an optical disc) in which a plurality of recording layers are laminated or bonded to the same substrate, as disclosed in Japanese Patent Application Laid-Open No. 2006-019019. Further, on a recording apparatus (such as a DVD recorder) on which recording is performed on a two-layer type (i.e., two-layer type) optical disc, the recording laser beam is focused on the side from the laser beam irradiation side to observe that it is located in front a recording layer (that is, on the side closer to the optical pickup head) (in the present application, hereinafter referred to as a "L0" layer, if necessary), thereby The rewritable method and the irreversible change recording method record information into the L0 layer. In addition, the laser beam passes through the L0 layer and is 097146734 200937390. The focus on the self-f beam illumination is the recording layer located at the rear (ie, on the side farther away from the photon read and write) (in the present application) 'When necessary, - hereinafter referred to as "Ll", whereby information is recorded into the L1 layer by heat in a rewritable method and an irreversible change recording method. For example, δ 'Japanese patent application Patent Publication No. 2006-019019 5 discloses a technique for pre-writing at least a portion of an area in which user data is recorded, such that when recording is performed in the L1 layer, the © laser beam is in the The laser beam is clearly transmitted through the recording area in the L() layer while focusing on the L1 layer to ensure recording efficiency on the innermost circumference and the outermost circumference of the u layer. In this double-layer type optical disc If the data is recorded in the L1 layer, it is necessary to illuminate the laser beam through the L0 layer. In this case, in the L0 layer through which the laser beam is transmitted, the data is recorded in some cases, and under other conditions. Do not record data. If above If the recording state of the L0 layer is not integrated, the amount of light of the laser beam irradiated on the L1 layer changes, because the transmittance of light transmitted through the L0 layer changes depending on whether or not the L0 layer is recorded. A so-called recording order is defined in which the transmittance in the L0 layer is set to be constant by previously making the L0 layer in the recorded state, and the data is appropriately recorded in the L1 layer. Here, when When recording is performed in the edge portions on the inner circumferential side and the outer circumferential side of the data region in the L1 layer, the laser beam irradiated from the lens is focused on the L1 layer in a conical shape. In the L0 layer, the 'laser beam is also Transmitted through an area on the farther inner circumferential side or the farther outer circumferential side of the edge portion of the data region in the L1 layer beyond 097146734 5 200937390. If the inner circumferential side or the outer circumferential side of the L0 layer including the inner circumferential side or the outer circumferential side as described above is included The entire transmitted area is not in the recording state', and the amount of light of the laser beam irradiated on the L1 layer is affected because there is a change in the amount of light transmitted through the L0 layer. Thus, for example, in the double layer In a write-once type recording medium (for example, a dual-layer type DVD-R) or the like, the data area in the L1 layer has a structure narrower than the structure of the data area in the L0 layer by a predetermined amount. The standard of the two-layer type DVD-R is determined as a value obtained by adding the gap long sound to the tolerance length, wherein the gap length is in the L0 layer through which the laser beam is transmitted when the focus is on the U layer. The sum of the radius of the circular area and the tolerance of the eccentricity between the layer and the L1 layer, and the tolerance length is the address in the boundary ^, the L0 layer, and each of the addresses defined in the L0 layer The tolerance of the position shift from the pre-set. Therefore, according to the standard, the area of the tribute in the L1 layer is set to be narrower in the two edges than the data area in the L0 layer. And. As a result, the recording unit β snail 41 of the data area in the L1 layer is defined to be relatively smaller than the recording capacity of the data area in the L0 layer. However, in the case of a two-layer type DVD-R having this data area, the data area capacity in the layer may be smaller than the data pit (data pi1 借 借 & stamping in each recording layer) The recording capacity of the data area of the double-layer and read-only type (for example, the dual-layer type DVD-ROM). Therefore, for example, the information for the configuration of the dual-layer type DVD-ROM is recorded by 097146734 6 200937390 In the case of the double layer type _4, it is almost impossible to have the amount of data to be recorded in the 11 layers in all the data exceeding the data area-domain capacity in the L1 layer of the double layer type _-R Record the problem of all the data. •—More specifically, the double-layer type of country__The record order in the LO layer and the L1 layer accounts for a maximum of 4.27 GB. On the other hand, the record volume of the double-layer type DVD_R is usually 4.2863GB in the L0 layer and 4. 2597GB in the L1 layer. Therefore, regarding the content of the content to be recorded on the double-layer type DVD_R〇M, the size of the material to be recorded in the L1 layer Exceeding 4. 2597GB 'cannot record data as it is, because it is impossible The data is placed in the double-layer type DVD_R2L1 layer. On the other hand, if the content data recorded in the data area of the double-layer type DVD_R〇MiL1 layer is 4.2597 GB or less, it can be considered that the content data can be recorded as it is. Up to the double-layer type DVD_R. However, in the double-layer type @DVD-R, the size of the data area recorded in the u layer is set to be smaller than the size of the data area recorded in the L0 layer. Therefore, if recording to u The size of the content data in the layer and the size of the content data recorded in the L0 layer are substantially equal to each other'. There is a problem that the content data cannot be recorded as it is. • In the dual-layer type DVD-β, as shown in Fig. 10(a) As shown in the figure, in order to comply with the record-order, the position of the outermost circumferential address χ (vertical line) of the data area in the L1 layer is usually from the position of the outermost circumferential address X of the data area in the L0 layer toward the inner circumferential side. The shift one corresponds to the length of the sum of the gap length and the tolerance length as described above. Further, the edge portion of the inner circumferential side of the data area in the L1 layer is 097146734 7 200937390, usually within the area of (4) ( (4) The portion of the fixed field is shifted toward the outer circumferential side by the length of the sum of the tolerance lengths as described above. The gate length and thus the positional relationship between the address in the L0 layer and the u layer are not correct throughout the entire surface of the disc. For the content of the inner side of the outermost circumference of the disc, if the end address of the data recorded in L0 is γ, the starting address of the data recorded in the li layer is Y (vertical line). That is, the recording start position 2 in the L1 layer is on the inner circumferential side of the recording end position in the L0 layer, and the recording end position in the u layer is always recorded in the L 0 layer. On the outer circumferential side of the starting position. Therefore, even if the content material recorded in the material area in the L1 layer of the dual-layer type DVD-ROM is 4. 2597 GB or less, there may be the following technical problem: it will be recorded in the dual-layer type DVD-ROM (which In the case where the content data on the feature having the substantially equal size of the content data recorded in the L〇 layer and the L1 layer is recorded as it is on the dual layer type DVD-R, the data cannot be recorded in the data area in the L1 layer. Inside. Specifically, as shown in FIG. 1(^), for example, if a 3.0 GB size inner valley recorded in each of the L0 layer and the L1 layer is recorded as it is on the DVD-DL The content data to be recorded in the li layer cannot be placed in the data area in the L1 layer, and will enter the lead-out area.

[Embodiment] A specific example of the recording apparatus of the present invention is a recording apparatus for recording content data onto a recording medium, the recording medium comprising: a first recording layer; and a second recording layer, the first The recording layer includes a first data area in which the content material is read by irradiating a beam of Ray 097146734 11 200937390, the second recording layer including a first one of which records content data by irradiating the laser beam through the first recording layer The beating area 'the recording device is provided with: - a recording device for recording the content data into the first data area and the second data area by irradiating the laser beam, the 'first reading device' for reading Taking capacity information indicating the recording capacity of each of the first data area and the first data area; - the second reading device is included in the content data towel or attached to the content data and is used to manage the content +Da ^ ^ Management information for under-shake; a division device for dividing the content data into the first to be recorded in the first data area according to the capacity of Beixun && Data to be recorded and a second region of the second data; and a control device for controlling the recording means to record the first data to the first data area and the second data to the second data recording area. According to a specific example of the recording apparatus of the present invention, when the content data is recorded on the recording medium including the first recording layer and the second recording layer, the content data is divided into the first data and the second data, and respectively the first The data and the second data are recorded in the first data area and the second data area. At this time, if the first data and the second data are separately recorded into one of the first data area and the second data area (that is, if the size of each of the first data and the second data is smaller than the first The size of each of the data area and the second data area is controlled, so that each of the first data and the second data is adjacently recorded to the first data area and the other one of the data areas The inner circumference (i.e., recorded in contact with the inner circumferential side)' and each of the first data and the second material 097146734 12 200937390 are recorded on the recording medium. Further, at the outer circumferential side of the first data and the second data, the intermediate area data is recorded until the outermost circumference is . Here, the content material to be recorded on the recording medium is usually dispersed, for example, in a download sale via a network such as the Internet; however, the content material may be as in a digital broadcast on a satellite and a digital television on land. Broadcasts are generally broadcast in digital methods. Further, the content material may have a format for recording the disc image material on the recording medium during the scatter or broadcast 。 stage. Regarding the recording medium in which the content material is divided into the first data and the second material and each of which is recorded in the data area in the different recording layer, there is, for example, a dual-layer type DVD-ROM (DVD-R0M double layer) and Double layer type DVD-R. Here, it is known that there is a difference in the structural structure of the two recording media. In the dual layer type DVD-ROM, each of the first recording layer (L0 layer) and the second recording layer (L1 layer) has the same capacity of the data area. The other side, in the dual-layer type DVD-R, the capacity of the data area in the L1 layer is set smaller than the capacity of the data area in the L0 layer in view of the gap length and the tolerance length. As a result, the capacity of the data area in the L1 layer of the dual-layer type DVD-R is smaller than the capacity of the data area in the L1 layer of the dual-layer type DVD-ROM. Therefore, for example, in order to record the content data of the dual-layer type DVD-ROM onto the dual-layer type DVD-R, it is necessary to change the area structure of the dual-layer type DVD-R, or to appropriately classify the content to the recording process. In the L0 layer and the L1 layer. However, in a specific example, first, by means of the first reading device, the reading capacity 097146734 13 200937390 information 'the capacity information indicates the recording capacity of the first data area and the second data area. At the same time, by means of the second reading device, the management information for managing: capacity = is read. Here, for example, the management information may be information indicating a candidate position added to the age point of the content described later, or may be information necessary for recording the candidate position of the device's own division point. This point is for recording a two-layer type DVD-title content material to a two-layer type Dm having a regional structure different from the area structure of the dual-layer type DVD-ROM for appropriately dividing the content material into the first data. And any information of the second information is included in the scope of "management information" in the specific example. In addition, information necessary for detecting the candidate position of the division point for the recording device itself, for example, listing such as a video manager Information (Vide〇Manager Inf〇rmati〇n, VMGI) and video title set information (Vide〇Title such as Secret (10), VTSI) IFO file (information file) as an example. More specifically, for example, in the IF0 file Medium is the boundary of the unit (the unit is the reproduction unit of the content data), and is also the error correction code (Err〇rc〇rrecti〇nc〇de, the boundary of the ec〇❹ block (the block is the data record unit) and Does not rely on the seamless playback nag (which indicates whether to ensure continuous reproduction) to ensure that the position is detected as the candidate position of the division point ^ the candidate position of the division point by dividing the narrative At this time, by executing the program of money (4), even the position of the ECC boundary can be added to the candidate position of the division point. Next, the content of the content is divided by the division candidate points described above. 097146734 14 200937390 According to the capacity information, it is judged whether the first data and the second data generated can be separately recorded in the first data area and the second data area. This * is not the ECC. The boundary, as detailed later, is close to the dummy data of the sector unit after the file system, so that the end of the data in the L0 layer matches the ECC boundary. Then, it is actually judged to be recordable. The H point is used as a dividing point to divide the content data, and the divided I data (that is, the 'first data and the second data') are respectively recorded in the first data area and the first > material area. At the time, for the content data of, for example, video data, it is possible to detect the position of the dividing point. In addition, when the division is performed at the point of division to be measured, the content data can be judged by There is a size which is allowed to be recorded in each of the area of the recording medium, and is appropriately divided. As a result, it is possible to preferably record the double-layer type of i-listing without changing the area structure of the double-layer type DVD_R. The content material, that is, it is possible to efficiently record the content material in response to various content materials without changing the regional structure of the recording medium. In one aspect of the specific example of the recording apparatus of the present invention, the control device will be * The address of the position of the maximum capacity of the second data area is shifted from the initial state to the farther inner circumferential side so that the recording capacity of the second data area is expanded up to at least a predetermined capacity. According to this aspect, the second data area narrower than the data area (ie, the data area in the 'L layer) is set in view of the gap length and the tolerance length (also 097146734 15 200937390, that is, the data in the L1 layer) The area is expanded to be positioned in the inner lead-out area as compared with the innermost circumference of the second data area, and in conjunction with the foregoing operation, the recording capacity of the second data area is increased by a predetermined size. Here, for example, the 'second data area can be expanded' such that the capacity of the second data area is substantially equal to the data area in the L1 layer of the dual layer and read-only type of media (eg, dual-layer type DVD-ROM) Recording capacity. Further, the "initial state" indicates the state of the area structure in the "second data area" determined in advance, and generally, it indicates the area structure of the recording medium (for example, double-layer DVD-R) of the double layer and writing once type status. At this time, the capacity of the second data area of the recording medium in the specific example becomes equal to the capacity of the second recording layer of the dual layer type DVD-ROM. As a result, it is possible to record the data of the dual-layer type DVD-ROM onto the dual-layer type DVD_R. Further, in this aspect, the control device may control the recording device to record the pre-data to at least one predetermined area adjacent to the inner circumference side of the first data area: the start position, at the latest after recording the first data . ^Assisting in this construction' by the pre-recording of the pre-data in the region of the region of the first recording layer corresponding to the gap length and volume described above: The area is “a predetermined area, a special column”, yL·—,,, and can be executed to the appropriate record in the second data area while observing the record order. 2 External 'pre-data only needs the most It is recorded before the content data is recorded in the second data area in the second recording layer 1 layer. Usually, the pre-097146734 200937390 data can be recorded in tandem with the content data recorded in the first recording layer. Alternatively, it is possible to record the pre-data at the time point when the recording medium is loaded onto the recording device before the start of the recording process. With this configuration, it is possible to interrupt the recording of the image data during the recording of the data. By reducing the process of recording pre-data and, for example, it is possible to reduce the load on the buffer memory of the loyalty, and the result is that it is possible to provide a highly recordable device for data recording/regeneration to be stabilized and obtained. A highly reliable recording medium. In another aspect of the specific example of the recording apparatus of the present invention, the control device (1) shifts the address of the starting position of the first-behicle region from the initial state to a farther distance. a circumferential side such that the recording capacity of the first data area is expanded until at least a predetermined amount of grain ' and (11) the address of the starting position of the second data area according to the displacement corresponds to the maximum capacity of the first data area The address of the position is shifted from the initial state to the farther outer circumferential side. 第二 The second data area set to be narrower than the data area is expanded to the second data area according to the length and the tolerance length of the sample The outermost circumference is positioned in the outer middle area, and the recording capacity of the first data area is increased by a predetermined size together with the above-mentioned operation. The first data area is extended to the first data area by the same method. Compared with the outermost circumference, in the outer intermediate area, and in conjunction with the above operation, the recording capacity of the first data area is increased by a predetermined size. Here, for example, the second data area may be Expanding such that the capacity of the second data area is substantially equal to the recording capacity of the 097146734 17 200937390 data area in the L1 layer of the double layer and only the media (eg, double layer DVD-calendar). The capacity of the second data area of the recording medium becomes equal to the capacity of the second recording layer of the dual-layer type DVD-ROM. As a result, it is possible to record the data of the dual-layer type DVD-ROM to the dual-layer type DVD-R. In addition, in this aspect, while expanding the second data area, the first data area is expanded by the same amount as the second data area. At this time, between the first data area and the second data area. The difference in size caused by the length of the gap and the length of the tolerance does not change, the order of recording is maintained, and an appropriate recording into the second data area can be performed. In another aspect of the specific example of the recording apparatus of the present invention, the dividing means detects the position of at least one of the division point candidates of the content data according to the management information, and divides the content data at the division point candidate, (i) At the partition point candidate, the sum of the size between the start position of the content material and the partition point candidate and the size of the file system for controlling the reproduction of the content material is equal to or smaller than the first data area. The maximum capacity, and (ii) at the partition point candidate, the size between the partition point candidate and the end position of the content material is equal to or smaller than the maximum capacity of the second material. According to this aspect, it is judged whether or not the content material can be divided in view of the size of the file system, and whether it can be recorded in the first data area in the L0 layer and the second data area in the L1 layer. At this time, it is possible to preferably determine the position at which the content material is divided. In addition, in this aspect, if a plurality of division point candidate positions 097146734 18 200937390 are detected, at each of the plurality of positions, the first data and the second content when the content is divided are determined. The data does not exceed the information indicated by the capacity information# < . The recording capacity of the first data area and the second data area, the dividing means can disclose the content to the user and divide the content material at the position of the dividing candidate based on the user's choice. By means of this configuration, the division point of the data can be determined according to the user's wishes. At this time, for example, if the recording size is smaller than the data of the entire recording capacity of the dual-layer type DVD-R, the division point can be determined according to the user's request, thereby (for example) avoiding recording on the outside of the disc. On the circumferential side. In another aspect of the specific example of the recording apparatus of the present invention, the control device controls the recording device to record a predetermined size of dummy material from the recording end position of the file system, the file system being used for controlling the reproduction of the content data. News. According to this aspect, even if the size of the first data recorded in the L0 layer is equal to or smaller than the size of the second data recorded in the L1 layer, it is possible to record the dummy data by recording the dummy data to The L1 layer + is performed in the area in the necessary L0 layer to perform an appropriate recording into the second data area. That is, the position of the layer jump is shifted to the outer circumferential side by recording the dummy data of the necessary size into the area in the L0 layer, so that the recording start position in the second data area is also shifted to the outer circumference. side. As a result, the recordable area in the second data area is increased so that all the second data can be recorded in the second data area. In other words, the size of the dummy data is calculated to satisfy this condition. 097146734 19 200937390 In addition, as described above, if the division point of the first data and the second data is not the ECC boundary, the adjustment can be performed by using the dummy data of the sector unit to record the data recorded in the L0 layer. The end portion matches the Ecc boundary. In addition, in this aspect, the 'control device is calculated according to: the recording capacity of the first data area, the recording capacity of the second data area, the size of the first data added with the size of the file system, and the size of the second data. Large/Jn of the dummy material With this configuration, it is possible to appropriately determine the size of the dummy material. In addition, even if the size of the first data recorded in the layer is equal to or smaller than the size of the data recorded in the L1 layer, it is possible to record the dummy data to record the second data to the L1 layer. The appropriate record in the second data area is performed in the area in the necessary L〇 layer. Here, the size of the dummy asset needs to satisfy the following conditions: the size of the first data, the size of the file system, and the sum of the size of the dummy data are equal to or smaller than the record valley of the first data area, and are equal to or greater than one implementation. All second data can be recorded in the size of the second data area. Usually by subtracting the difference between the size of the first data and the size of the file system and the size of the second subject by the difference between the recording capacity of the first data area and the recording capacity of the second data area The value obtained is the minimum size of the dummy material to be recorded. By calculating the size of the dummy material in this way, it is possible to appropriately record the second data. In addition, even if the size of the first data and the second data are smaller than the recording capacity of the data area and the second data area of 097146734 20 200937390, it is possible to suppress unnecessary data recording by calculating the minimum necessary size of the dummy data. • Alternatively, in this aspect, the control device can shift the address corresponding to the position of the maximum capacity of the second data region from the initial state to the farther inner circumferential side, so that the recording capacity of the second data region is expanded until At least one predetermined capacity. With this configuration, the second data region (i.e., the data region in the L1 layer) which is narrower than the first data region (i.e., the data region in L0 |) is set in view of the gap length and the tolerance length. It is expanded to be smaller than the innermost circumference of the second data area only in the inner lead-out area, and together with the foregoing operation, the recording capacity of the second data area is increased by a predetermined size. Here, by way of example, the second data area may be expanded such that the capacity of the second data area is substantially equal to the data area in the L1 layer of the two-layer and read-only type of media (eg, dual-layer type DVD_R〇M) Recording capacity. Further, the "initial state" indicates the state of the area structure in the "pre-determined first data area", and generally indicates the area structure of the recording medium (for example, double-layer DVD-R) of the double layer and writing once type In this case, the capacity of the second data area of the recording medium in the specific example becomes equal to the capacity of the second recording layer of the dual-layer type DVD-ROM. As a result, it is possible to use the dual-layer type DVD-ROM. The data is recorded on the dual-layer type DVD_R. Further, in this aspect, the control device can control the recording device to record the pre-data to the start position of the first data area 097146734 200937390 at the latest before recording the second data. The inner circumferential side of the disposed inner side is adjacent to at least the financial region. By means of the structure & the pre-data is recorded in advance in the region of the lead-in area in the first recording layer corresponding to the gap length and volume described above In one of the sums of the lengths of the lengths (Ling A (the specific area of the "introduced area", it is possible to follow the same procedure as in the case of A Guangzhong inch 2. The appropriate record in the data area. In addition, the 'pre-data only needs to be recorded at the latest before the content data is recorded in the second data area in the second recording layer (ie, the 'L1 layer). Usually, the pre-data can be The content material is recorded in the first to the last recording layer. Alternatively, the pre-data may be recorded at the time point when the recording medium is loaded onto the recording device before the start of the recording process. With this configuration, the data is recorded. In the process, it is possible to reduce the process of recording pre-data by interrupting the recording of image data and (for example) it is possible to reduce the load on the buffer memory of the recording device. The result 'is possible to provide a highly reliable recording device for data The recording/regeneration is stabilized and a highly reliable recording medium is obtained. Further, in this aspect, the control device can be based on: the first data area winter recording capacity, the expanded second data area recording capacity, and the file system added. Calculate the size of the dummy data by the size of the first data of the size and the size of the second data. With this configuration, it may be appropriate Judging the size of the dummy data. In addition, even if the size of the first data recorded in the L layer is equal to or smaller than the size of the second data recorded in the L1 layer, it is possible to record the dummy data record 097146734 22 200937390 to It is necessary to be in the recorded condition to record the second data into the area in the LO layer in the L1 layer and perform the appropriate recording into the second data area. Typically, by the recording capacity and expansion from the first data area The difference between the recorded capacity of the material area minus the difference between the size of the first data and the size of the file system and the size of the second data is the minimum amount of dummy data to be recorded. By calculating the size of the dummy data in this way, it is possible to appropriately record the second data. Further, even if the sizes of the first data and the second data are smaller than the recording capacities of the first data area and the second data area, respectively. It is still possible to suppress unnecessary data records by calculating the minimum necessary size of the dummy tribute. Alternatively, in this aspect, the control device (i) may shift the address of the start position of the second data region from the initial state to the farther outer circumferential side such that the recording capacity of the second data region is expanded until at least one Predetermining the capacity, and (ii) according to the address of the starting position of the shifted second data region, the address corresponding to the location of the maximum capacity of the first data region can be shifted from the initial state to the farther outside Circumferential side. With this configuration, the second data area narrower than the first data area is expanded to be positioned in the outer middle area as compared with the outermost outer circumference of the second data area in view of the gap length and the tolerance length. And in conjunction with the above operation, the recording capacity of the second data area is increased by a predetermined size. In the same manner, the first data area is expanded to an intermediate portion located outside the outermost circumference of the first data area and, in conjunction with the above operation, the recording capacity of the first data area 097146734 23 200937390 is increased by a predetermined size. Here, for example, the second data area can be expanded such that the capacity of the second data area is substantially equal to the data area in the L1 layer of a two-layer and read-only type of media (eg, a dual-layer type DVD-ROM) Recording capacity. At this time, the capacity of the second data area of the recording medium in the specific example becomes equal to the capacity of the second recording layer of the dual layer type DVD-ROM. As a result, it is possible to record the data of the dual-layer type DVD-ROM onto the dual-layer type DVD-R. Further, in this aspect, while expanding the second data area, the first data area is expanded by the same amount as the second data area. At this time, the difference between the size of the gap between the first data area and the second data area caused by the length of the gap and the length of the tolerance does not change, the order of recording is maintained, and an appropriate recording into the second data area can be performed. Further, in this aspect, the control device is based on: a recording capacity of the expanded first data area, a recording capacity of the expanded second data area, a size of the first data to which the size of the file system is added, and Second, the size of the data, calculate the size of the dummy data. With this configuration, it is possible to appropriately judge the size of the dummy material. Furthermore, even if the size of the first material recorded in the L0 layer is equal to or smaller than the size of the second material recorded in the L1 layer, it is possible to record the second data by recording the dummy data to the need to be recorded. The appropriate recording into the second data area is performed into the area in the L0 layer in the L1 layer. Generally, the sum of the size of the first data and the size of the Tan file system is subtracted from the difference between the recording capacity of the expanded first data area and the recording capacity of the second data area of the extended 097146734 24 200937390 The difference between the size of the two data is obtained - the value is the minimum size of the dummy material to be recorded. By calculating the size of the dummy material in this way, it is possible to properly record the second data. In addition, even if the size of the first data and the second data are smaller than the § recording capacity of the first data area and the second data area, it is possible to suppress unnecessary data recording by the minimum necessary size of the leaf dummy data. © In another aspect of the specific example of the recording apparatus of the present invention, the predetermined capacity is at least equal to or larger than the size of the data area set for the two-layer and read-only type of media. According to this aspect, it is possible to substantially equalize the data structure of the double-layered and write-type recording medium in the specific example and the data structure of the double-layer and read-only type of media. Therefore, as described above, it is possible to record the content material in the same condition as that recorded on the media of the double-layer and the read-only type as it is on the recordable type recording medium in the specific example. In another aspect of the specific example of the recording apparatus of the present invention, the predetermined area is a length in the radial direction corresponding to the tolerance length and the gap length to the area of the small one and the tolerance length indication to be defined in the first - in the recording layer: an allowable range of the relative positional shift between the address of the predetermined two places and the address of the predetermined bit in the second recording layer, the gap length indicating the second record of the focus of the laser beam The maximum value of the half point of the laser beam on the first recording layer on the layer and the relative deviation between the first recording layer and the second recording layer: = 097146734 25 200937390 The sum of the allowable maximum values. According to this, the predetermined sequence of the length in the radial direction corresponding to the sum of the length of the second data region and the length of the tolerance is recorded in the first recording layer by the pre-recording sequence (usually The portion of the portion of the region that is introduced into the region is maintained, and it is possible to preferably perform the recording at the innermost circle of the second data region. Incidental "*limit length 4 indicates to be defined in the first record The allowable range of the relative position shift (or self-position shift) between the address at the predetermined position in the design in the layer (for example, the 'predetermined direction of the location') and the address of the position in the second recording layer In other words, the "tolerance length" is the relative position between the address at a predetermined position in the design defined in the first recording layer and the address at the 骇 position defined in the design in the second recording layer. The shifting material, in other words, the "tolerance length" is the allowable range of the positional shift between the position in the first recording layer defining the predetermined (four) in the design and the position of the predetermined button on the actually manufactured recording medium. second In the recording layer, the position where the silk is located in the design is defined. The actual manufacturing record _ the position of the _ position to move the mosquito.

In the material area. More specifically, the first data is recorded into the first data area 112 included in the first recording layer, and the second data is recorded into the second data area 122 included in the two recording layers. In addition, a data record for finalizing the optical disc 100 is also performed. As shown in FIG. 4, first, the optical disc 1 is loaded on the drive module 21, and the disc inspection is performed (step S101). Here, for example, various control information necessary for data recording is obtained, or the operation of the signal recording/reproducing device 213 is performed under the control of the cpU 214 to execute the 〇pc program. Or it may be judged whether the loaded optical disc has just been a two-layer type optical disc. Further, at this time, the volume information in each of the recording layers of the optical disk 1 is detected. More specifically, the recording capacity DG of the first-data area 112 in which the user data is to be recorded in the side-recording layer and the second data area 097146734 37 200937390 will be in the middle of the axis (four), at least until the recording procedure End it. Then 'check the information to be recorded (step (4)). The material 'reproduced as a reward (information file) for management information on the content material included in the content material or the like. In addition, information about the size of the content material, the size of the rights system area 116, or the like can be read. The read information is held in the Dragon 222 at least until the recording process ends. Further 'here, whether or not the position of the _u candidate point is added to the content material (step S1〇3). Here, L] candidate point system - is the position of the candidate for determining the u point of the data division I. u candidate points need to be full, so that they are cell boundaries, which are rainbow boundaries, and which are the locations where the data is continuously reproduced and not ensured by the seamless thief flag (which refers to whether the material is continuously regenerated) By performing the process described later, even if the LJ candidate point is not an ECC boundary, it can be added to the candidate position of the division point. If the location information indicated to the y LJ candidate point is added (step si〇3: YES), the location of the LJ candidate point is detected and obtained (step S104). If the additional information indicating the location of the LJ candidate point does not exist (step S103: NO), under the control of the cpu 221, the video manager information (Video Manager Information, ¥ 骱 1) and the video title of the content data are extracted and analyzed. The information (Video Title Set Inf〇rmati〇n, VTSI) obtains position information satisfying at least one condition of the LJ candidate points described above, 097146734 38 200937390 and detects the position of the LJ candidate point (step S105). Next, an LJ candidate point is selected from one or a plurality of LJ candidate points (step - S106). Then, when the data is divided into the first data to be recorded into the L0 layer 110 and the second data to be recorded into the L1 layer 120 at the selected one of the LJ candidate points, the size C0 of the first data is obtained. The size C1 of the second material (step S107). Here, the size C0 of the first material is the sum of the size between the head of the Video ❹ Manager (VMG) and the obtained one of the LJ candidate points and the size of the material such as the file system. In addition, the size of the second data C1 is the size between the LJ candidate point and the end of the content material obtained by the data. Next, it is judged whether or not each of the data areas has a recording capacity large enough to record the material to be recorded therein (step S108, step S109). More specifically, it is judged whether the recording capacity DO of the first material region 112 is equal to or larger than the size CO of the first data (step S108), and then or simultaneously determines whether the recording capacity D1 of the second data region 122 is equal to or greater than The size of the data C1 (step S109). - As a result, if the recording capacity of any of the data areas is equal to or larger than the size of the data to be recorded (step S108: YES, and step S109: YES), it is judged that the recording capacity of the first data area 112 in the L0 layer 110 is L1. Whether the difference between the recording capacities of the second data regions 122 in the layer 120 (i.e., DO - D1) is equal to or smaller than the difference between the size CO of the first data and the size of the second data Cl 097146734 39 200937390 (also That is, CO - Cl) (step S110). Here, the value of DO - D1 indicates the difference between the capacity of the first data area 112 in the L0 layer 110 and the capacity of the second data area 122 in the L1 layer 120, which are configured to be even in the data area. The order of recording is still observed in the edge portion. In general, the value of DO - D1 corresponds to the data size of the sum of the gap length and the tolerance length described above in the outer circumferential edge portion of the data region and the gap length described above in the inner circumferential edge portion corresponding to the data region. And the sum of the data sizes of the sum of the tolerance lengths. As a result of the judgment, if C0 - C1 is equal to or larger than DO - D1 (step S110: YES), the previously selected LJ candidate points are determined as LJ points, and the data is divided at the LJ point (step S111). Next, in the recording program, the material is recorded in each recording layer (step S112). In this example of operation, as a basic rule, the first material is first recorded into the first data area 112 in the L0 layer. When the end address of the first material (i.e., the LJ point) is recorded, the recording to the first material area 112 is ended, and the layer for performing recording is changed from the L0 layer 110 to the L1 layer 120. More specifically, the signal recording/reproducing device 213 controls the optical pickup 212 to change the state of the laser beam LB and focus on the L1 layer 120 of the optical disc 100. Next, in the second data area 122, the second data is recorded from a position as the start address, which is inwardly wider than the position corresponding to the LJ point in the L0 layer 110, the width corresponding to the above description. The sum of the gap length and the tolerance length. 097146734 40 200937390 Figure 5 is a layout diagram showing the structure of the optical disc in the radial direction of the optical disc on which the data is recorded. In Fig. 5(a), the f material is divided and recorded, 'so that the recording capacity DG of the first data area 112 is equal to the size -co of the first data. On the other hand, in the case where the size co of the first data and the size Ci of the second data are smaller than the recording capacities DO and D1, as shown in FIG. 5(b), the unrecorded portion is not left in the per-(four) domain. The outer_side upper 1 fills the unrecorded portion from the intermediate portion of the bead material until the outermost circumference. As a result, as described in (d), if the value of the size of the domain (4) is calculated Ε ', the dummy data is usually recorded into the dummy material area 117 in the first data area 112. Here, the 'virtual material is, for example, a material having a size of Ε or the like and the dummy material is recorded from the recording end position of the housing system area 116 in the first data area 112. At this time, if If the dividing point set to the LJ point in the dividing program does not match the Ecc boundary, the size of the dummy data is adjusted so that the end of the data in the (3) layer 11〇 matches the ECC boundary. Specifically, a fan is added. In addition, even if the size calculated in the dividing program described later is zero, if the LJ point does not match the ECC boundary, the dummy data of the sector unit is still recorded, so that the L0 layer is The end of the data is matched with the Ε (χ boundary. It can be simultaneously formed with the file system area 116 or the like - the front-to-start virtual record data file system area 116 or the like is recorded in the first data area 112. On the inner circumference. Next, after the recording in the data to the first data area 112 and the second data area 097146734 122 41 200937390, the various controls for controlling data recording or regeneration will be used. The information or the like and the dummy material (for example, "〇〇h" material) or the like are recorded in the lead-in area 111, the lead-out area 121, and the intermediate areas jig and 123. Even in this case, in order to comply with the recording order After the control information or the like is recorded in the lead-in area Hi in the L0 layer 110, it is still preferable to record the control information or the like to the record in the L1 layer 12 that is wider than the L0 layer 110. In the lead-out area 121 of the area where the control information or the like is present. Further, after the control information or the like is recorded in the intermediate area 113 in the layer L, the control information or the like is preferably recorded. To the intermediate area 123 of the L1 layer 120 corresponding to the area in the L0 layer 110 in which the control information or the like is recorded. After the material is recorded, the recording operation is ended. Incidentally, the recording order may be the lead-in area 111, The order of the L〇 data area 112, the L0 intermediate area 113, the L1 intermediate area 123, the L1 data area 122, and the lead-out area 121. Alternatively, the recording order may be the lead-in area 111, the L0 data area 112, and the L1 data area. 122. The order of the lead-out area 121, the L0 intermediate area 113, and the L1 intermediate area 123. Again, in Fig. 4, 'on the other hand, if C〇-C1 is smaller than do_D1 (step S110: No)', the dummy data area is calculated. The size E of 1Π (step S113). Typically, the size C0 of the first data and the file system area 116 are subtracted by the difference between the recording capacity do of the first data area 112 and the recording capacity D1 of the second data area 122. The value obtained by the difference between the sum of the size and the size C1 of the second data is at least 097146734 42 200937390 size E of the virtual data area to be recorded (ie, 'E = (D〇 - Dl) - (CO - Cl)). Here, the value obtained by adding the size E of the dummy data area 117 to the size c of the first data is set to the new C0 (step S114), and again, the recording capacity of the data area is compared with the record to be recorded. The size of the data (step S108, less illusion 〇 9). In addition, if the recording capacity of any of the data areas of the optical disc 1 is smaller than the size of the data to be recorded (step S108: No, or step S109: No), it is not possible at the selected Lj candidate point. Divide the information. Here, it is determined whether the selected LJ candidate point is the last lj candidate point detected, that is, whether the location information indicating the unselected LJ candidate point is determined is determined (step S115). As a result, if an unselected LJ candidate point is detected (step sn5: NO), the point of the next LJ candidate point is obtained (step S117), and when the data is divided at the LJ candidate point, the program calculates the data size. Start (step sl7). On the other hand, if there is no longer a detected lj candidate point, or if it has been judged that all of the LJ candidate points are (step SU5: YES), the judgment data cannot be recorded to the optical disc (step SU6). ), and the recording process ends. By means of this operation, it is possible to perform division on the basis of the data of the video data, for example, the position of the brake data point, and the data is determined by the determination of whether or not there is a recording medium. The recordable size in the data area is appropriately divided. As a result, the content data of the two-layer type excitation can be preferably recorded to the two-layer class (10) D _ R. That is, in response to various materials, data can be effectively recorded. 097146734 43 200937390 Incidentally, when the layer is changed in reproduction, that is, when the layer jump is performed in the reproduction, the reproduction of the video stream is interrupted in some cases. Therefore, it is desirable for the user viewing the content to change the layer at the point where it is as comfortable as possible. Therefore, by adding the position information indicating the LJ candidate point, it is possible to notify the recording device side that the layer jump is only comfortable for the user who views the video image. Therefore, it is possible to set the layer jump position to a more comfortable position without using a more complicated method such as image recognition.

Further, in the process of determining that the LJ candidate point is the LJ point in step S111, the user's judgment may be added. More specifically, for example, if one of the selected U candidate points satisfies the condition of the LJ point (step S108: Yes, step sl9: Yes, and step S110: YES), the location information indicating the LJ candidate point is stored in the memory 222. Then, as shown in step SU5, the selected U candidate point is determined. Whether it is the last u candidate point detected, and if there is another extracted candidate, the next-u candidate point is selected and the judgment is performed as described above. As a result of the judgment, the indication is performed in the same manner. The location information of the LJ candidate location of the U point is stored in the memory port 222. As described on 097146734 200937390, if two or more LJ candidate points that can be LJ points are stored, then the host computer 22 is not The illustrated display device or the like informs the user of the location information of each LJ candidate point. Then, in the same manner, the user inputs an LJ candidate for determining the set as the LJ point via an unillustrated input device. Point information, by The information determines the LJ candidate point as the LJ point, and divides the data at the LJ point. With this configuration, the ❹LJ point can be determined in the case where the user's judgment is added. (Second operation example) The reference pattern will be explained. A second operational example of the inventive recording device. Incidentally, the same constituent elements in the drawings carry the same component symbols. In the second operational example, a record is constructed to have a medium smaller than the double-layer and read-only type. The recording area (second data area 122) in the L1 layer 120 of the recording medium of the one-time type recording capacity is expanded, so that the recording capacity D1 is substantially equal to the double-layer and read-only type of medium. The recording capacity of the recording area in the L1 layer, and the content data is recorded. More specifically, as shown in FIG. 7(a), the second data area 122 in the L1 layer 120 - the end address (ie, the internal The edge portion on the circumference is displaced to the side of the lead-out area 121 adjacent to the inner side to thereby increase the recording capacity D1 of the second data area 122. Further, in this aspect, in order to maintain the recording order, Pre The data is recorded into a predetermined area (i.e., pre-097146734 45 200937390 recording area 115) in the L0 layer 110 (generally, in the lead-in area 111) in which the end of the second data area 122 is considered to be shifted. The address corresponds to the length of the sum of the gap length and the tolerance length. On the other hand, on the outer circumferential side of the data region, there is a length in the radial direction corresponding to the sum of the gap length and the tolerance length described above. The recorded area is formed at a recording end position of the first material in the first data area 112 in the L0 layer 110 and a position on the L0 layer 110 corresponding to the recording start address of the second material in the L1 layer 120. In order to maintain the order of recording. At this time, the difference between the sum of the size of the first data C0 and the size of the file system area 116 and the size C1 of the second data will be at least greater than the capacity between the first data area 112 and the second data area 122. difference. Therefore, it is judged whether the difference between the sum of the size of the first data C0 and the size of the file system area 116 and the size C1 of the second data is greater than the difference between the capacity of the first data area 112 and the capacity of the second data area 122. . As a result, if it is judged to be smaller than, the dummy material is recorded in the dummy material area 117 having the size calculated to satisfy the aforementioned condition. If it is judged to be greater than or equal to, the dummy material is not recorded. Next, using Figs. 6 and 7, an explanation will be given regarding one aspect of the second operation example associated with the recording program. Fig. 6 is a flow chart conceptually showing the flow of the second operational example. As shown in FIG. 6, first, as in the program of 097146734 46 200937390 shown in the first operation example shown in FIG. 4, the optical disc 100 is generally loaded on the drive module 21 to perform the disc inspection step _). .

In addition, 鸪^_1汉疋勹^ draws information about the size of the content data, the size of each divided data at the time of execution division, the size of the file system area 116, 丨,, + # or the like By. The read information is held in the memory 222 until the end of the recording process. The content data is divided at the determined LJ point (step s2〇2). Next, an operation or calculation for changing the structure of the data area for recording the content material on the optical disc 100 is performed (step S203). Specifically, in order to make the recording capacity of the L1 recording layer read in advance in the material inspection reach a predetermined amount, the shift amount of 30, the end address after shift, or the like, use the shift amount, The end address after shifting, or the like, shifts the end address of the second material area 122 to the lead-out area ι2 i adjacent to the inner circumference side to increase the recording capacity. Here, the predetermined capacity is, for example, the recording capacity (usually 4.27 GB) in the L1 layer of the dual-layer and read-only type of media. If the recording capacity is increased in this manner, the end address of the second data area 122 after the shift is specified at a position of 24. 0 mm from the inner circumference of the disc. 097146734 47 200937390 Next, in order to comply with the recording order 'According to the shifted end address of the second data area 122', the size of the pre-data previously recorded in the lead-in area 111 is calculated and the area in which the pre-data is to be recorded (ie, pre- Recording area 115) (step S204) ^ Here, the pre-recording area 115 is generally an area on the lead-in area ill formed in the area on the L-layer 11〇, which has a shift from the second data area 122 The subsequent end address is the length in the radial direction corresponding to the sum of the gap length and the tolerance length. The size of the pre-data is stored in the table, graph, or equation in the memory (4) 5 according to the pre-recorded area. 115 (usually the data constructed from the introduction of data) is calculated. Next, the size E of the dummy material region -X 11 f of the region on which the dummy material of the first material is recorded on the first data region 112 on the L 〇 layer m is calculated (step S205). Generally, the size of the at least the dummy data area 117 to be recorded is "between the recording capacity DO from the first data area 112 and the recording capacity D1 of the second data area 122 of the hurricane-& The difference is obtained by subtracting the difference between the sum of the size C0 of the first data p π and the size of the file system area 116 and the size Cl of the second material (i.e., E = (DO - D1) ^ (c〇- Cl)) Here, the 'virtual data area 117 is an area having the size E described above from the end position of the file system area 4 1丨b. No. "%, for example, will be such as 00h. The data is recorded to the dummy data area ip by Y. The first data is written from the end of the record of the virtual data area Π7. Next, the data is recorded into each recording layer. First I, No, the calculated pre-097146734 48 200937390 data is recorded in the predetermined pre-recorded area 115 on the L 10 (step S206). After that, the content material and related materials are recorded in each of the other areas (step S2G7). In this operation, as a basic rule, the first data is first recorded in the first data area L in the L0 layer 110. At this time, the slot system area ιΐ6 recorded with the data such as the file system is formed from the start address of the first data area 112, and the dummy data area 117 of the β dummy data calculated in the above manner is recorded from the file system area. The end address of ιΐ6 is formed. Further, the _f material is recorded in the area after the end address of the dummy material area 117 in front-to-back. When the thread address of the first data (i.e., the LJ point) is recorded, the recording in the first data area is ended. The layer of the performer's execution record is changed from the L0 layer 11〇 to the u layer 12〇. More specifically, the No. 7 δ recording/reproducing device 213 controls the optical pickup 212 to change the state of the laser beam LB and focus on the optical disk [I layer 12 。. Then, the calculated record start address records the second data, so that the record of the second data is completed at the end address of the second data area 122. In the case where the size Ci of the second data is smaller than the recording capacity of the second data area, as shown in FIG. 7(b), the unrecorded area is not left on the outer side of each data area, and is The intermediate area attribute data fills the unrecorded area up to the outermost circumference. Then, after the data is recorded in the first data area 112 and the second data area 122, the various controls that will be used to control data recording or reproduction are 097146734 49 200937390:=like and dummy data (for example, , " The data) or the like is recorded in the U1 area, the lead-out area 121, and the intermediate areas ιΐ3 and 123. Even in this case, in order to comply with the recording order, the control information or the like is recorded to the LG. After the introduction area (1) in the layer mountain, it is still preferable to record the control information or the like to the extraction area 121 of the area in which the control information or the like is recorded in the corresponding layer of the u layer 12" Further, after the control information or the like is recorded in the intermediate area 113 in the layer 110, the control information or the like is preferably recorded to the record corresponding to the L0 layer 110 in the L1 layer 120. In the intermediate area 123 of the area where the control information or the like is controlled. After the data is recorded, the recording operation is ended. Incidentally, the recording order may be the introduction area 丨11, the L 〇 data area 112, the L0 intermediate area 113, L 1 The order of the intermediate area 123, the L1 data area 122, and the lead-out area 121. Or the 'recording order may be the lead-in area 11 L0 data area 112, L1 data area 122, lead-out area 121, L0 intermediate area 13, and L1 intermediate area The order of 123. Next, in particular, the area structure of the optical disc 100 in the second operation example will be explained. Fig. 7 is a view showing that the optical disc 1 has recorded contents in the second operation example. Schematic conceptual view of the region structure in the radial direction. The optical disc 1〇〇 in FIGS. 7(a) and 7(b) is set such that the innermost circumference of the second data region 122 is shifted to adjacent The lead-out area 121 on the inner circumference side. Thereafter, in order to maintain the recording order, the 097146734 50 200937390 pre-recording area 115 for pre-recording the introduction data is set in a predetermined area in the lead-in area 111. Here, regarding the set The recording area 115, for example, sets an area having a length corresponding to the sum of the gap length and the tolerance length from the end address of the shifted second resource area 122. system The area 116 is recorded on the inner circumferential side of the first data area 112, and the dummy data area 记录7 in which the dummy material is recorded is set in a predetermined area from the end address of the file system. The dummy data area 117 is determined to have The difference between the recording capacity D of the first data area 112 and the recording capacity D1 of the expanded second data area 122 is subtracted from the first '""" The value obtained by the difference between the size of the size C0 and the weight system and the size C1 of the second data recorded in the first data area 122. That is, the dummy material E is calculated by the equation e = (DO - D1) - (CO - C1) and the dummy material E is recorded into the dummy data area 117. Fig. 7 (a) is a view showing the area structure of the optical disk 1 , and if the recording capacity D1 of the second turtle data area 122 is equal to the size C1 ' of the second material, the content data is recorded in the area structure. On the other hand, in the case where the size C0 of the first data and the large *C1 of the second data area are smaller than the recording capacity D0&D1*, the recording of the second data is calculated and recorded as shown in FIG. 7(b). The start position, the record end address of the first data, and the dummy data area 1 are such that the record of the second poor material is completed at the end address of the shifted second data area 4 122. At this time, the 'unrecorded area is not left on the outer circumferential side of each data area' and the unrecorded area is filled by the intermediate area to the outermost 097146734 51 200937390 circumference. With this configuration, it is possible that The content data record I reads the class type on the tablet in the same condition as that recorded on the two-layer type and type: (third operation example) The third embodiment of the recording apparatus of the present invention will be explained with reference to the drawings In the operation, the same constituent elements in the drawings carry the same component symbols. For example, in the second operation example, the recording capacity is smaller than the double-layer and the recording capacity of the read-only class is double-layered and the write-type-type record is recorded. The recording area in the media ❹ of the media (ie, the 'second data area 122') is expanded by 120, which is substantially equal to the double layer and the u-layer of the read-only type of media. More specifically, The starting address of the second data area 12 2 (that is, the edge portion of the outermost circumference) of the 'u layer 12' is shifted to the side of the intermediate area 丨2 3 adjacent to the outer circumferential side to To increase the second capital The recording capacity D1 of the material area 122. In addition, in this aspect, in order to maintain the recording order, the end address of the first data area 112 in the L0 layer 11 (i.e., the edge portion of the outermost circumference) is phased. The intermediate portion 113 adjacent to the outer circumferential side is displaced by the same length as the shift amount of the start address of the first-bean material region 122 described above. At this time, the content lean material can be recorded to the L〇 layer 11〇. It is considered that the starting address of the shifted first-behicle region 122 is in a predetermined region corresponding to the length of the gap length and the length of the tolerance. 097146734 200937390 At this time, the size of the first data C0 and The difference between the sum of the size of the file system area 116 and the size C1 of the second data area will be at least greater than the difference between the capacity of the first data area 112 and the capacity of the second data area 122. Therefore, the first Whether the difference between the size of the data size C0 and the size of the broadcast system area 116 and the size C1 of the second data is greater than the difference between the capacity of the first data area 112 and the capacity of the second data area 122. If it is judged to be less than The data record 炱 has a dummy data area 117 calculated to satisfy the size of the foregoing condition. If it is judged to be greater than or equal to, the dummy data is not recorded. Next, using FIG. 8 and FIG. An explanation of one aspect of the third operation example is shown in Fig. 8. Fig. 8 is a flow chart conceptually showing the flow of the third operation example. As shown in Fig. 8, first, as shown in the first operation example shown in Fig. 4. in

Next, the data to be recorded is normally checked in the program shown in the first example shown in Fig. 4 (step S102). - In the first division of the Μ(4)4 for the real money, the second program is set to the point (step S2G1). At this time, by designating the D1 of the capacity of the DO (4) field and using a new stub judgment program, the new DO is made by the data area~-by adding the second companion order to the original DO. Obtained by the increase in size. 097146734 53 200937390 Next, the content data is divided at the determined LJ point (step S202). Next, an operation or calculation for changing the structure of the data area for recording the content material on the optical disc 100 is performed (step S301). Specifically, in order to make the recording capacity of the L1 recording layer read in advance in the material inspection reach a predetermined capacity, the shift amount, the end address after the shift, or the like is calculated, and the shift amount and the shift are used. The end address, or the like, shifts the start address of the second data area 122 to the intermediate area 123 adjacent to the outer circumferential side to increase the recording capacity. At the same time, the end address of the first data area 112 in the L0 recording layer is shifted by the same amount as the shift amount of the second data area 122 toward the intermediate area 113 adjacent to the outer circumferential side. Here, the predetermined capacity is, for example, the recording capacity (usually 4.27 GB) in the L1 layer of the dual-layer and read-only type of media. Next, the size E of the dummy material area 117 on the first data area 112 on the L0 layer 110 is calculated, and the dummy data area 117 is an area in which the dummy material of the first material is recorded (step S302). Generally, at least the size E of the dummy data area 117 to be recorded is subtracted from the difference between the recording capacity D0 of the expanded first data area 112 and the recorded capacity D1 of the expanded second data area 122. The value obtained by the difference between the size of the size of the data area C0 and the size of the file system area 116 and the size C1 of the second data (i.e., E = (DO - D1) - (C0 - Cl)). Here, the dummy material area 117 is an area having the size E described above set from the end bit 097146734 54 200937390 of the file system area 116. For example, data such as "00h" is recorded in the dummy material area 117. The first data is self-defective - the write end address of the data area 117 is written. • Material 'records the data into each recording layer (step S3G3). In this example of operation, as a basic rule, the first data is first recorded in the first-data area 112 in the L-layer 11〇. At this time, the file system area n6 recorded with the data such as the file system is shaped from the start address of the first data area 112 and the dummy data area 117 of the dummy data calculated in the above manner is recorded from the file system area. The end address of 116 is formed. Further, the first data is recorded in an area between the end address of the dummy material area 117 and the end address of the shifted first data area 112. When the end address of the first material (i.e., the LJ point) is recorded, the recording to the first data area 112 ends. Then, the layer on which the recording is performed is changed from the L0 layer 11A to the li layer 12A. More specifically, the signal recording/reproducing device 213 controls the optical pickup 212 to change the state of the laser beam LB and focus on the 11 layers 12 of the optical disk 1''. Next, the second data is inward from the start address of the second data region 122 shifted as described above (generally, inwardly corresponding to the position corresponding to the LJ point in the L〇 layer 11〇) The position of the gap length and the width of the tolerance length is recorded. Then, after the recording of the data into the first data area 112 and the second data area 122 is finished, various control information for controlling data recording or reproduction or the like and dummy data (for example, "〇〇h" data) will be used. Or a similar 097146734 55 200937390 is recorded into the lead-in area 11 and the intermediate areas 113 and 123. Even in this case, in order to comply with the recording order, the introduction control area or the like in which the control information or the like is recorded in the L0 layer 110 is preferably recorded in the L1 layer 120. This corresponds to the area in the L0 layer 110 where the control information or the like is recorded. In field 121. Further, 'after controlling the information or the like to be recorded in the intermediate area 113 in the area, the control information or the like is preferably selected to the corresponding iLM 110 in the L1 layer 12, and the control is contained (4). In the middle area 123 of the area of the person. After recording the data, the recording operation is ended. Incidentally, the order of recording may be the order of the lead-in area, the L〇 data area 112, the L0 intermediate area 113, the L1 intermediate area 123, the L1 data area 122, and the lead-out area 121. Alternatively, the recording order may be the order of the lead-in area 111, the L0 data area 112, the L1 data area U2, the lead-out area 121, the L0 intermediate area Π3, and the L1 intermediate area 123. Fig. 9 is a layout view showing the area structure of the optical disc 100. If the recording capacity C1 of the second material area 122 is equal to the size C1' of the second material after expansion, the content data is recorded in the area structure. In the optical disc 100 of Fig. 9, the recording is performed such that the edge portions on the outermost σ卩 circumference of the first data area a? and the second data area 122 are displaced to the middle adjacent to the outer circumferential side. Areas 113 and 123. Here, regarding the address amount to be shifted, for example, an address amount 122 for realizing the following result is expanded so that the double layer is written once and written once in the L1 layer 120 of the recording medium of 097146734 200937390 = The recording amount of the second data area 122 (which is narrowed by the length of the gap and the length of the tolerance) matches the capacity of the data area in the L1 layer 12 of the dual-layer and read-only 3L medium. At this time, the recording capacity of the second data area 122 and the recording capacity of the L1 layer of the recording medium U layer 120 are double-layered and written. The socially equal double-layered and read-only type of media in the L] layer m is related to the content data, and can even be recorded ❹ - subtype 2 (four) ^, G1 cut double layer and written in addition, the record can be based on the record order After the record in the media.仃, even if it is not pre-recorded in advance [Simplified description of the drawing] Figure 1 is a plan view showing a single-sided double-layer type, which is an example of the substantial structure of the basic structure of the disc, and A schematic diagram of the regional structure in the radial direction of the recording device in the system, and a recording layer of the non-mother of the recording device, FIG. 2 shows the region surname structure _ i ' in the direction of the light direction of the single-sided double-layer type.
