Does the CD-ROM include a 650MB CD?丄 DVD_R〇M disc. In addition, next-generation optical discs with a recording capacity exceeding that of dirty are under development. The DVD transmits R ^ T recordings and single-layer discs with only 4.7 cents. However, it has 8 dual-layer discs. In order to give these & view = private, 8 times of recordable details must be used. However, in this case, basically doubling 'is very disadvantageous to the user. Improving records recognizes that it will be very necessary. However, due to the improvement of the optical disc technology, a method is needed that effectively records data at a conventional speed. The 8.5GB recordable DVD is immediately introduced to the market. The structure of a conventional rewritable optical disc is described with reference to FIG. 1A. Figure m depicts the structure of a drinking disc. The structure of the lead-out area 6 20054 · 3 (lead out area) and the lead-in area (ieacj_in area) shown in FIG. 1A is almost the same. In particular, the lead-in area of the rewritable optical disc as shown in Fig. 1A includes a test area for determining an optimum recording energy. FIG. 2A and FIG. 2B show the structure of a dual recording layer disc in which data is recorded in a write-once (disc_at_nce) mode. In this write-once mode, data is written on the disc by the writer at one time (ie, within a single-recording session), and a predetermined data mode is recorded on a blank lean area where no data is recorded, so even if there is The blank recording area cannot be used to record other materials. —Generally, the “write-once” mode is used to back up a large amount of data. In this mode, a large amount of data is recorded on a write-once disc. On the dual recording layer disc 10 shown in FIG. 2A, the data is recorded in an opposite direction (otp) from the track, and on the disc 20 shown in FIG. 2B, the data is parallel to the track (ρτρ). Referring to FIG. 2A, when a conventional technique is used to record data on a dual recording layer disc 10φ in a direction of ττρ opposite to track tracking, user data is recorded at The user data on the data area 12 of the recording layer L1 is first reproduced on this layer li, and the remaining user data is recorded on the data area 15 of the recording layer L2. The areas 丨 3 and η located outside the outer border 19 of the data areas 12 and 15 are all occupied by a predetermined data pattern for marking, a dataless area. The predetermined data pattern 'is, for example, data having a lead-out attribute. An area occupied by a predetermined data pattern used to mark a data-less area 'is generally called a connection area, and it distinguishes between a lead-in area and a lead-out area. ) 17. Of the overall data area on the recording layer L2, a blank area 16 in which no user data is recorded, becomes a connection area occupied by a predetermined data pattern for marking a data-free area. As shown in FIG. 2B, the optical disc 20 includes a lead-in area 21, a data area 22 of the recording layer L1, a lead-out area 24, a data area 25 of the recording layer B2, and connection areas 23 and 26 of the recording layers L1 and L2.

如圖2A和2B所示的記錄方法可以同樣的方式應用於 唯讀光碟和可重寫光碟。 以上描述的傳統技術，以一次寫入模式（disc_at_〇nce ) 在光碟上A錄資料，這需要額外的資料記錄時間，在沒有 A錄使用者資料的區域來記錄具有引出屬性的默資料模 式。另外，由於完全沒有❹資料區域之外的區域，光碟 使用效率不高。 【發明内容】 資料: 一種在光碟中配置區域的方法，當記錄 =吏用效率;採用此方法之資料記職再;= >根據本發明特徵’其所提供的光碟 ::，層:從光碟的内周到外周的方向上，包；心 上记錄貝枓的使用者資料區域；連 以標誌沒有記錄使用者資枓 °°或，在其上記錄用 量，確 试，卢姑千丨从广 者料的預疋資料模式；以及剩純 "w ’、品域，根據被記錄的使用者資料的數、 200540^3^ 定每一記錄層的使用者資料區域的大小和位置，且連接區 域和剩餘區域緊挨著每一層的使用者資料區域而配置在從 光碟内周到外周的方向上。The recording method shown in Figs. 2A and 2B can be applied to a read-only disc and a rewritable disc in the same manner.

The connection area records a predetermined data mode to indicate that no user data is recorded. According to still another feature of the present invention, the method for arranging light emitting areas with a plurality of recording layers provided by the present invention includes: determining the size and position of the user data area of each recording layer according to the amount of data to be recorded; In the direction from the inner periphery to the outer periphery, a connection area and a fiber area are arranged next to the user data area of each recording layer, and the connection series of the towel records a predetermined data mode to indicate that no user data is recorded. In order to make the above and other objects, features, and advantages of the present invention more apparent, the preferred embodiments will be described below in conjunction with related formulas, and described in detail below. [Embodiment] The attached invention is related to the actual situation, and the sub-descriptor = 11, where the same denotation symbol always represents the same-component explanation. This is explained below with reference to Lai Tu handle. once In the embodiment of the present invention, a case where data is written in a number of times (diSC-at-9 20054Θ8τ3 & M-type brother recorded on an optical disc having a plurality of recording layers) will be described as an example of the embodiment. In the embodiment In #data, when recording on a disc with multiple recording layers in disc-at-once mode, the total amount of details to be recorded is known in advance and the total amount is less than the recordable of the disc In the case of the total amount, determine the user data area and size of each recording layer, so that user data of the same size is recorded in the parent layer of multiple recording layers. #Determining the size of the user data area of each __ recording layer Time 'determines the location of the user data area of each record layer. When the location of the user data area of each record layer is determined, the connection area of each record layer and the remaining ship area check and / Or the size. According to the embodiment of the present invention, 'the predetermined data pattern with the attribute of export need not be recorded in the entire remaining data area where no data has been recorded, so the data recording time is less than the traditional data recording. The connection area is an area in which a predetermined data mode is recorded to mark data that is not recorded. The predetermined data mode is, for example, data with an export attribute. According to the embodiment of the present invention, in addition to the user data area and the connection area, A dedicated area (exdusi for Hongye) is provided on the remaining peripheral area. The exclusive area is used by the data recording and / or reproduction device for a special purpose. For example, the test area for the best month control (OPC) Can be allocated to the exclusive area. Another area other than the test area can be allocated to the exclusive area, and the exclusive area can be designated as a reserved area. The user data is recorded in a rewritable area Prior to the optical disc, the optimal energy control OPC passed preliminary tests to determine the optimal recording energy of the data recording and / or reproducing device. 200540 & 3 & Figures 3A and 3B describe the structure of the optical disc according to the first embodiment of the present invention. The dual recording layer of this optical disc records data in disc_at-once mode. On the optical disc 100 shown in FIG. 3A, the data is inverse track 〇τρ (opposit e track pass) direction. On the optical disc 200 shown in FIG. 3B, data is recorded in a direction parallel to the track PTP (paraliei track pass). Referring to FIG. 3A, when the data is written once in the 0TP direction (disc -at-〇nce) mode when recording on the dual recording layer of disc 100, the data recorder and / or playback device can identify the amount of user data to be recorded, and if the amount of user data is less than the recordable amount of disc 100 In total, the user data areas 113 and 123 of the recording layers Li and L2 are determined, and as a result, the same amount of user data is recorded on each of the recording layers L1 and L2. Since the internal boundaries of the user profile areas 113 and 123 have been determined, their external boundaries are automatically determined. When the user data areas U3 and 123 are determined, in the outer peripheral direction of each recording layer, the positions and / or sizes of the connection areas H5 and 121 and the remaining areas 117 φ and 119 are determined. The positions and / or sizes of the connection areas 115 and 121 and the remaining areas 117 and 119 can be determined in various ways. For example, if the size of at least one of the connection areas 115 and 121 or the remaining areas 117 and 119 is predetermined, all other connection areas 115 and 121 and the remaining areas 117 and 119 can be determined.
