Description of the Invention: [Technical Field] The present invention relates to a method of writing a cymbal film, and also for recording a data onto a disk for faster recording. A method and apparatus for accessing information required for writing a disc, and a write once disc suitable for the above method and apparatus. [Prior Art] New information can be repeatedly recorded on a rewritable disc on which information has been recorded. However, when new information is recorded on a disc, it is impossible to erase the information that has already been recorded or to re-record the information at the position where the information has been recorded, in order to record. The updated information of the funds recorded on the disc must be assigned a new location. ^ Usually, only the information that was last updated is valid. Therefore, in order to read the last updated information, it will be assigned to an update area of the data area, and the data. The recorded and/or regenerative device measures the last updated information by detecting an update area in which the updated information is recorded. When a large amount of information is recorded in the update area, it takes a long time for Lu to detect the required information. ^When the defect management is performed by the data recording and/or reproducing device once, on the chip, there is a defect for generating a defect when the disk is written once: the bellows and the recording state indicating that the disk is written once. Information area 3. Unlike the rewritable disc's, according to the characteristics of writing a disc, the updated information cannot be reversed because of the lack of update information of the official information. The position of the current deposit §fl has been recorded, and the updated information must be recorded. Therefore, it is necessary to allocate a relatively large update area. Usually, the update area is allocated on a lead-in area or a lead-out area. However, sometimes the update area may be allocated to the data area in order to update the number according to the user's instructions.
當使用寫入一次碟片所需的最後被更新之資訊被記錄 在分配於資料區的更新區中時’並且當指示更新區分配於 資料區的資訊和指示更新區的位置的資訊被包括在最後被 更新之資訊中時，即使分配於導入區或導出區的整個更新 區被搜索，也不能檢測到最後被更新之資訊或者記錄最後 被更新之資訊被記錄的位置。 即使資料記錄及/或再生裝置檢測到最後被更新之資 訊被記錄在分配於資料區的更新區中，如果更新區很大， 查找記錄在更新區中的最後被更新之資訊也可能會使用較 長的時間。 【發明内容】 本發明提供了一種寫入一次碟片，它具有.以預定方法When the last updated information required to write a disc is recorded in the update area allocated to the data area' and when the information indicating the update area is allocated to the data area and the information indicating the location of the update area are included in In the last updated information, even if the entire update area allocated to the lead-in area or the lead-out area is searched, the last updated information or the position at which the last updated information is recorded cannot be detected. Even if the data recording and/or reproducing apparatus detects that the last updated information is recorded in the update area allocated to the data area, if the update area is large, the last updated information of the search record in the update area may be used. Long time. SUMMARY OF THE INVENTION The present invention provides a write once disc, which has a predetermined method

The access information area records an area in which access information is recorded, wherein the access information indicates the location at which the update information is recorded, such as the defect management information required for the recording and/or reproducing apparatus to write a disc. The access information and access information area will then be clarified. The data area includes a first backup area, a user data area, a management area, and a second backup area. In the disc-distribution process, based on the specification of the write-first disc in this embodiment, the first temporary disc management area in the knife-import & However, the 篦-匕3 in the area is in the initial 匕: the second temporary disc management area and the second backup area system area. In the process of the secondary disc, the user's selection is assigned to the capital and FIG. 3B_ is a detailed structural diagram of the dual-recording layer L0 disc of the present invention. ® 3 is shown as the first recording layer 3 Α: Π ', 3 Β is shown as a structural diagram of the second recording layer U. The structure of the recording layer L0 of the drawing 5 is the same as that of the single recording layer 11 I3l669^ifdoc shown in Fig. 2. The structure of the recorded layer L of the second recording layer L1 shown in Fig. 36 is similar. However, in the second recording layer . . . , the access tribute area is not allocated to the second internal area, and the two slate disc management areas are allocated to the second data area. The area to write one disc includes the first temporary disc management area of the first temporary disc management day. The first position and the size of the temporary disc management area are recorded η-^ well known as H. In order to make an i device with dual recording layers: ^^=进进!!

The first-temporary disc management ^ The disc management area and the fifth temporary disc management area are assigned to the write-sub-disc with double recording layer of ίr=?. In other words, in addition to the well-known first temporary disc management area and the second temporary official area, when the (four) has a double recording layer of the writer - the second is the beginning of the user, or the record and / or regeneration m The fifth temporary disc management area is allocated to the second data area. The method assigned to the area in which the disc is written once, such as the temporary disc management area, and the method of recording the data in the area are now explained. The time disc>| g area is recorded in the end of the write-disc (flnalizatiQn), the temporary disc for managing the write-disc 12 I316699pifd〇c ^ (temporary disc management structure) ^ area. The termination operation of the in-sub-disc prevents the recording of data to the disc once again. When the user chooses to prohibit writing to the disc record again or cannot write data to the disc once, the disc is written once. The temporary disc management structure includes a temporary disc defect list (temp〇rary_defect list), a temporary disc definition structure (temp〇rary_definition structure), and a spatial dot matrix map (ah ratio conversion). The Temporary Call for 4 pieces of missing list includes information indicating the area in which the defect occurred and information indicating the replacement area. The temporary disc definition structure for managing the temporary disc defect list includes a position indicator indicating a position at which the temporary disc defect list is recorded, a position indicator indicating a position of the recording space dot map, and a position indicating the backup area allocated to the data area. And size information and information indicating the location and size of the temporary disc management area allocated to the data area. The spatial dot map displays the state of the φ data record written to the disc in a dot pattern by assigning different bit values to the cluster in which the data is recorded in the cluster unit (data recording unit) and the unrecorded data. When a write once disc is loaded into the recording and/or reproducing apparatus, it is necessary to quickly sell and regenerate the last updated temporary disc management structure from the write once disc, in particular to update the temporary disc definition structure to A write once disc is used in this device. Generally, when a write once disc is loaded into the recording and/or reproducing apparatus, the recording and/or reproducing apparatus determines how to manage the writing of the disc by reading information from the lead-in area and/or the lead-out area. The film and how to record or reproduce the 13 1316 Na if.doc data. If the amount of information recorded in the lead-in area and/or the lead-out area is large, after writing the --disc remaining load, a longer coffee is required to prepare the record or the data. Therefore, the concept of a temporary disc management structure is adopted, and a temporary disc management structure that records data on a disc or writes a disc from a disc is recorded in a separate guard from the defect management area. On the disc management area, and assigned to the lead-in area and/or the lead-out area. By storing only the disc time defect list that has been updated and recorded several times in the disc management area and the last valid information factory in the temporary disc definition structure, the recording and/or reproducing apparatus is only read from the defect management area. Take the valid information 'to make the quick access to the write-sub-disk information access & n, so when the write once the disc is finalized, record the temporary disc management structure on the temporary disc management area, also That is, the temporary disc defect list and the temporary disc definition structure are finally recorded on the disc management area. 5A and 5B are diagrams illustrating the steps of recording data to a user data area and a backup area in accordance with an embodiment of the present invention. Fig. 5A shows a user data area '圊5B' indicating a backup area. The method of recording the user data into the user area Φ includes the continuous recording mode and the random recording mode. User data is continuously and orderly recorded in the continuous recording mode, and user data is randomly recorded in the random recording mode. Areas 1 through 7 indicate the units that perform the verification after recording. The recording device writes the user profile to the area 1 and verifies whether the user profile is normally written ' or a defect is generated in the area 1. If a defect is found, this portion is designated as the defective area', that is, defect #1. Moreover, the 14 13166 Xing if.doc recording device writes the missing (4) household data to the backup area 4. User data that has been written to the missing fo#l is overwritten in the backup area called the replacement correction. The recording device? Area 2 writes the user data and verifies that the user data is normally written. If a defect is found. This part is designated as the defective area, ie defect #2. Similarly, the corresponding corresponds to defect #2_换#2. *And, in the area 3 towel, the defect is illusory, and the substitute is generated. In the area 4, since no defect of the defect is found, the defect area does not exist in the area 4. Ϋΐ If you write the person and verify the user profile, pre-stabbed the record operation eight 'that is' if the user presses the exit (ejeCt) button or the user of the recording operation is recorded, the recording device will be generated with "1. Defective area defect #1, defect #2 and defect #3 related ^ = Write the temporary disc defect column finely into the temporary disc management area J. The management structure of the disc defect list is written into the temporary map or expected. The second: t:! The operation system is the work unit of the mosquitoes in the user's intention. In this book, the table is not loaded from the writer - the disc is loaded and executed for a period of time. The recording device unloads the write-sub-disc - condition: ===, the recording operation #2 starts, the user data is recorded. Γ is employed, and based on the result write operation is the same as the record operation #2, the user f With the recorded, replacement #4 采i i is written to areas 5 to 7, and defect #4, defect and wheel 5 are generated. When recording operation #2 ends, record 15 13 l'66Q^, fdoc will be placed Information related to defect #4 and defect #5 is written to the temporary disc management area as a temporary disc Trap list # 2. Manage temporary discs missing 2 = management structure is also written to the temporary disc management area as a temporary disc structure #2. As shown in Figure 2, Figure 3A, Figure 4A and Figure 4B, When the disc = the official area and the backup area are assigned to write a disc, the temporary disc management area and the backup area are used in a predetermined order. For example, as shown in FIG. 3A and the figure, when writing with a double recording layer The data used to enter the disc is written as an opposite track path (opposite track pat; h), that is, from the first inner region of the first recording layer L0 to the first outer region of the first recording layer L And the second internal area of the recording layer L1 is recorded to the second record: the second external area records the data, and the data of the backup area is recorded from the first backup area of the first/recorded layer L0. When the first backup area is full, the second backup area, the third backup area, and the fourth backup area are used in order. Similarly, the temporary disc management structure is managed from the first recording layer. The area starts recording. When the first temporary disc management area is full of φ, it is updated. The disc management structure is recorded in the second temporary disc management area assigned to the second internal area of the second recording layer L1. When the second temporary disc management area is full, the recently updated temporary disc management structure is recorded. In the third temporary disc management area assigned to the first data area of the first recording layer L0. In the present embodiment, the first temporary disc management area and the second temporary disc management assigned to the inner area of the recording layer The zone writes the necessary part of the disc. However, the temporary disc management area assigned to the data area is optional by the user. Therefore, from the internal area 16 assigned to the recording layer

In these three embodiments, the access information indicates where the update information is recorded, such as the disc management structure, and in particular the location of the temporary disc definition structure. This _ update information indicates that the recording and/or reproducing apparatus uses the information that should be recognized during the initial period when the disc is loaded into the recording and/or reproduction. Moreover, the area in which the update information is recorded is referred to as the update area. In these three embodiments, the update information is a temporary disc definition knot, and the update area is a temporary disc management area. 17 131669, Qfd〇c 实施In the embodiment, the at least one main access λ s of the recording main access information is allocated to one of the input/distribution areas or an internal area of the primary disc, and once The access information area is assigned to a temporary disc management area. When the write once disc is loaded, the recording and/or reproducing apparatus first acquires the main access information by accessing the main access information area. The recording and/or regenerative acquisition identifies the temporary disc management area of the temporary disc definition recorded from the main access information, and then obtains the temporary disc management area of the temporary disc management area. Access information. Since the recording and/or reproducing apparatus can identify the position of the last disc definition structure that is last updated from the secondary access information, the time for finding the last updated temporary disc definition structure in the temporary disc management area is used. Can be reduced. According to the present embodiment, as shown in Fig. 2, Fig. 3A and Fig. 4A, the access information area main access information area assigned to the write once disc is allocated. Since if the main access gong area is large or multiple main access information areas are allocated, it will take longer to obtain the main access information, so the size of the main access information area & preferably _ non-essential) It is limited by minimizing the number of primary access information recorded in the primary access information area and the number of primary access information updates. In order to minimize the number of primary access information updates, when the disc management area of the temporary disc definition structure that was last updated is changed, the main access information is recorded in a recording unit block of the main: area.

As shown in Fig. 3 and && eight match two I: temporary disc management area to the fifth temporary disc management = knife with write-disc, the temporary disc definition structure includes the first product disc Location information from the management area to the fifth temporary disc management area. The number of recording unit blocks of the right structure can be used to identify the temporary disc management area of the last updated temporary disc receiving structure. This wear:: The management area to the first temporary disc management area is assigned to write-: person, slice 'and the order of the first, second, third, fourth, fifth temporary disc management area The use is detailed. If the main t child takes the information 'that is called the disc definition structure, it is not recorded in the main access secret. The recording and/or playback device thinks that the last disc definition structure that was last updated is recorded in the first temporary disc. In the slice management area. If the gro disc definition structure is only recorded in the first block of the main access information area, the temporary disc definition structure that the playback device considers to be last updated is recorded in the second temporary disc management. If the temporary disc definition structure is recorded in the first and second blocks of the main access information area, the recording and/or reproducing apparatus considers that the last updated disc definition structure is recorded in the third temporary disc management area. . Similarly, if the temporary disc definition structure is recorded in the first to third pieces of the main access job, the recording and/or reproducing apparatus recognizes that the last modified disc definition structure is recorded in the fourth temporary disc. Slice management H. And the strong disc temporary disc definition structure is recorded in the main access information (4) S - to the fourth piece of the towel, the recording and / or playback device thinks that the most 19, 13 l'6^9^if.doc is updated after the temporary disc The definition structure is recorded in the fifth temporary disc management area. As described above, the recording and/or reproducing apparatus records the recording unit block of the 6S time disc from the main access information area, and the recording unit block of the definition structure is finally updated (IV) to define the structure of the structure. And the temporary disc collection structure recorded last in the main access information area is reproduced. Therefore, the recording and/or reproducing sorrow can identify the location information of the temporary disc from the temporary disc definition structure. According to this embodiment, the size of the main access information area depends on the number of temporary disc management areas allocated to the write-sub-disc. That is, if there are N temporary disc management areas on the write-disc, the main access information contains (N-1) recording unit blocks. (4) Accessing the temporary disc definition of the information area, ,,. Constructed well (but not necessarily) is repeatedly recorded in a record temporary disc definition structure size equal to one magnetic area size (2κ 2 ^), and if the record single peach size is 64 Κ bytes, a _ time disc The definition structure can be repeatedly recorded 32 times in a record block. A cut-off format that can be touched in the magnetic zone unit is disclosed in US paste = No. 9. According to the error correction format of the U.S. Patent Application No., the temporary disc definition structure is repeatedly recorded in the recording unit block of the ::64K byte, and the secret of successfully reproducing the temporary disc is greatly improved. That is, even if the temporary disc definition structure (access f message) has been recorded 32 times; an error has occurred 'if 32 repetitive record temporary disc definitions: construct = 20 • 13166 ® 9ifd〇c record And/or the regenerative device may have one less temporary disc definition structure that may be error corrected to obtain access information. The district information is determined by how many sub-regions are divided into a temporary disc (package. Hole area). ' Show as - divided - access to the information area and multiple sub-areas; the data structure description of the official film area of the disc. As the main memory _ ^ set " 1 ^ ^ secret structure from the face of the government / / regenerative access information area recorded in the temporary disc receiving structure of the record unit dragon identification record the last temporary disc definition structure Sub-region. 2 pieces of information are recorded in the main access f, which is recorded == temporary disc definition structure can be repeatedly recorded in - A as shown in Figure 7, the temporary disc management area is divided into first to Mth The second temple disc S area, and when the sub-area is sequentially used in the direction from the first temporary disc management area to the Mth temporary disc management area, if a temporary disc definition structure is not completely Recorded in the secondary access information area, the recording and/or reproducing apparatus considers that the last temporary disc definition structure is recorded in the first temporary disc management area. > If a temporary disc month definition structure is only recorded in the first block of the secondary access information area, the recording and/or reproducing apparatus considers that the last temporary disc definition structure is recorded in the second temporary disc management area . If the temporary disc definition structure is recorded in the first and second blocks of the secondary access information area, the record and / 21 13166SQif doc = the device considers that the last temporary disc # defined structure is recorded in the third time disc management Area. According to this embodiment, the A small amount of the secondary access quota assigned to each temporary disc zone depends on the number of sub-areas assigned to the disc 2 per ship. That is, if there is a meta-area in the temporary disc management area, the human access information area should include at least (M) records. FIG. 8 is the main access information area and the secondary storage in one embodiment of the present invention. Take the explanatory diagram of the shell condition area. According to the present embodiment, the write-first disc is as shown in Fig. 4B. When the disc is initialized, only the fifth disc, the tube, and the area are allocated to the disc of the data area. The main access information area includes four material blocks. In the actual customs towel, the fifth temporary disc management area includes 35,000 blocks' and is divided into units of 4,_ blocks (except for units containing only 3,000 pieces). That is, the fifth temporary disc management includes nine sub-areas. Therefore, as described above, the information access unit block is accessed a second time. Dry 8 When the write-sub-disc is initialized, or when the first temporary disc is enabled, the main access information is not recorded in the main access information area. If the position of the last temporary disc definition structure is changed to the second disc management area, the recording and/or reproducing apparatus passes the signal to the main surface, and the structure is indicated to indicate the last. The temporary disc structuring is recorded in the second temporary disc management area. , ~ For example, the position of the last temporary disc definition structure is changed to the fifth temporary disc, and the management area, recording and/or reproducing apparatus records the temporary disc by the first second and fourth blocks of the main access information area. The slice definition structure indicates that the last 22 I316699Pifd〇c temporary disc definition structure is recorded in the first area of the fifth temporary disc management area. 9A and 9B are diagrams for explaining a secondary access information area according to another embodiment of the present invention. According to the present embodiment, the first disc management area, the fourth temporary disc management area, and the fifth temporary disc management area are initialized when the disc is initialized as shown in FIGS. 3A and 3B. A disc assigned to the data area. Therefore, as described above, since five temporary disc management areas are allocated, the main access information area includes four recording unit blocks. In the present embodiment, the third temporary disc management area and the fourth temporary disc management area each include 16,000 blocks, and as shown in Fig. 8, the fifth temporary disc management area includes 35,000 blocks. FIG. 9A is a diagram showing the data structure of the third temporary disc management area, and FIG. 9B is a diagram showing the data structure of the fourth temporary disc management area. The third temporary disc management area includes four sub-areas. Therefore, the secondary access information area included in the third temporary disc management area includes 3 pieces of recording unit blocks. Since the fourth temporary disc management area is the same as the third temporary disc management area, the secondary access information area included in the fourth temporary disc management area also includes three recording unit blocks. The fifth temporary disc management area is divided into a plurality of units each having 4,000 recording unit blocks (except units including only 3,000 recording unit blocks), and includes nine sub-areas. Therefore, as described above, the secondary access information area included in the fifth temporary disc management area includes eight recording unit blocks. As described above, according to the first embodiment, the recording and/or reproducing apparatus can further access the main access information by recording the main access information to the main access information area and accessing the information to the sub-access information area. Quickly access the location where the last structure is recorded.呷乃疋我疋 Now I will clarify the record and/or the last temporary disc definition of the main memory information access, 5 one person ^ > a my ',, ° structure. According to the example, when the main access information and the secondary access genre regenerative device are recorded, the signal and/or === ί # zone are recorded. If the f message is not recorded at all, the definition structure is recorded in the first temporary disc, the m disc is a blank disc, and the first temporary disc management area is accessed. If there is no recorded data in the =^^4 area, the recording and/or reproducing device recognizes the white disc and starts initializing it to use this: fire,. If the data is recorded in the first temporary disc management area, the -彔 and/or regenerative device manages the temporary disc definition structure from the first temporary disc. W is fetched. If the bedding material is recorded in the main access information area, the recording and/or reproducing device reproduces the temporary disc definition ^f by accessing the block in which the last recorded data is accessed. The recording and/or reproducing device is located - the last recorded data ί A, and identifies in which temporary disc management area the most recent, sheet A structure is recorded. In addition, the 'recording and/or reproducing device can also recognize the last temporary temporary record from the regenerated temporary disc receiving structure. The disc f(4)(4) is large, 1, and the root information is used to identify whether to give the second disc. Access the information area. Moreover, if a secondary access information area is allocated to the temporary disc g area, the recording and/or reproducing apparatus can recognize the size of the 24 I3^mfd〇c - human access poor area. If there is no temporary structure in the definition of the structure, find the last temporary in the Meili area: ii: However, if the secondary access information area is assigned, the temporary disc definition structure has the final temporary disc definition: - r, i. The same as the first embodiment, in the second implementation, the secondary access is allocated to the lead-in area or the inner area of the write-disc. Access to the shell "is illustrated in Figure 10 is not the present invention - the existence of the embodiment. As shown in Figure 1〇, the data structure of the disc definition structure is the same = the flag of the temporary disc management area. ^疋义,,,. In the present example, ‘5 has included the indication of the last temporary disc definition,’. The first mark information of the temporary disc management area is recorded as the last temporary disc definition. The first mark information includes 4 bits from ^ to .... For example, when b4 to b7 are 〇〇〇〇b, you can define the last temporary disc definition structure. 25 I3l6^Qifdoc can be used in the disc's official area. When b4 to b7 are 0001b, manage ί 敢ί The slice definition structure is recorded in the second temporary disc sarcophagus film II & field is 001%, the final temporary = slice 疋 structure can be defined and recorded in the third temporary disc f area, when b4 When the first temporary disc definition structure is recorded in the disc 0 area, and the heart (4) is 诵b, the last temporary disc definition structure of the management ^ is recorded in the fifth temporary disc = two mark information. It includes 4 bits from bG to b3. Now, the second mark information in the fifth sub-time == of the 5 sub-areas is divided into the second sub-area as the example two to 133 is _%, the last temporary disc can be defined to be recorded in the first - In the sub-area, when bQ to w is the face &amp;, the final temporary disc definition structure of :f is recorded in the second regional meaning to define the last temporary disc set to be 4°=in the 4 second domain When 'bQi, jbu_b, the medium-time disc definition structure is recorded in the fourth sub-area. When the bb to b3 is 1GGGb, the last temporary disc structure can be defined in the fifth sub-area. ', the temporary information used in the ancient information ^ structure is recorded to mention the possibility of η temporary disc definition structure, this temporary disc only defines the knot, preferably (but not necessarily) is repeatedly recorded in the - record block Second Embodiment This embodiment is similar to the first embodiment described above. However, unlike the first 26 palladium cases, in the present embodiment, the secondary access information is not recorded in the write once, slice. Therefore, in this embodiment, the secondary access information area is not allocated to the disc = disc management area, and the main access information and the main access information area in the first embodiment are respectively represented as access information and access information. Area. The recording and/or reproducing apparatus for writing the primary disc of this embodiment carries the recording of the user data to the lean area and the recording of the temporary disc receiving structure to one of the temporary disc management areas. If the temporary disc management area of the recently updated temporary disc definition structure is full, the recently updated temporary disc definition structure cannot be recorded in this temporary disc management area, and is recently updated = temporary disc definition The structure is based on a temporary disc definition structure in which H is recently recorded in a temporary disc management area as an access information is recorded in a recording block of the access information area. The playback device that writes the primary disc of the present embodiment accesses the access area, and based on the plurality of recording blocks in which the access information is recorded, determines to record the last updated temporary disc in the temporary disc management area. The last temporary disc management area of the fixed structure. Then, the reproducing apparatus obtains Φ from a recording block and finally retrieves the last updated information recorded in the last temporary disc management area. The reproducing device acquires the location information of the last temporary disc management area from the last updated access information, and the last temporary disc management area records the temporary disc definition structure that is updated after the dare. Finally, the reproducing device acquires the last updated temporary disc definition structure from the last temporary disc management area. Since the temporary disc definition structure recorded as the access information in the access information area is recorded in the access information area only when the temporary disc management area in which the temporary disc definition structure of the record is changed is changed, the temporary disc is recorded. The slice definition node 27 I3i_§ifdoe structure may be different from the last modified disk definition structure. - In the embodiment as described above, when the temporary disc definition structure used for accessing information is recorded, this temporary disc definition structure is preferably (but not necessarily) repeatedly recorded in one recording block. If the size of this temporary disc definition structure is equal to the size of one magnetic area (2K bytes) and if the size of the recording block is 64K bytes, a temporary disc definition structure can be reverse recorded in one record block. 32 times. An error correction format disclosed in U.S. Patent Application Serial No. 6,367,049, the disclosure of which is incorporated herein by reference.
