A structure. The magnetic volume structure is recorded in a magnetic volume structure area 101. The details of the magnetic volume structure will be described with reference to FIG. 4. An AV file area 601 is recorded with an AV file (AV file-a) 641 and an AV file. (AV file-a) 642, one file registration (AV file-a), AV file (AV file-b) 643, and one AV file (AV file-b) 643, one file registration (AV file-b) 644. A basic file structure area 6 3 2 of the latest file structure area 6 3 1 records the basic file structure. The basic file structure contains a control file (data building) with information related to the AV eaves case 6 4 5. One file registration (data file) 646 of the control file 645, one a V directory (AVDir) 647, one file registration (AVDir) 648, one file set description item 649, one root directory 6 50, and root directory 6 5 0 A file login (genmufa Concisely say Lai continued: Page 1235361 Record) 65 1.

For example, a virtual address is used to specify the file set description item 6 4 9 and the recording position specified by the logical disk group description item 4 4 5. Even when the file set description item 64 9 is recorded in a new When recording location (logical address), you can still access the file set description item 649 and its new recording location by updating the logical address in VAT 653. Among them, VAT 653 describes the virtual addresses and the logical addresses. Correspondence between the latest file structure area 63 1 This space management structure is recorded in each space management structure area 622. This space management structure contains an unconfigured Shima registry 6 5 2. A VAT structure is recorded in the VAT structure area 6 0 2 of the latest file structure area 6 3 1. The VAT structure includes VAT 653 and VATICB 654. The record information section 1 1 1 contains " counting unit 1 4 1 for designating a valid registration unit number, and, 'the plurality includes the first registration unit 1 4 2 And the registration unit of the second registration unit 143 ". The counting unit 141 records only the first counting block 17 indicating the identification number of the first registration unit 1 4 2 and the first registration block 176 and the registration magnetic area which are recorded in the first registration unit 142. The second registration block 177 of the number 663, in which the registered magnetic area code -32- sighs _ continued 1235361 (28) The code 6 6 3 indicates the location information of the latest file structure area 6 3 1. By comparing a version number 4 6 3 of the first registration block 1 7 6 with a version number 6 6 2 of the second registration block 1 7 7, it will be noticed that the second registration block 1 7 7 is valid. Register the latest registration block of sector number 6 6 3. 1.5 Space Management Structure This space management structure will be described below with respect to Figure 1. A space management structure is a structure for managing location information of an unallocated area, wherein the unallocated area is a continuous area of recordable data in the magnetic volume space. After recording some data on a disc, the space management structure must be recorded. The unconfigured space registration 1 5 5 in a space management structure includes a description item label 1 8 5 indicating that the registration is an unconfigured space registration, and the location information of at least one unconfigured area in the magnetic volume space (as shown in the figure) The example shown in 1 is the location information of an unconfigured area # 1 1 8 6, the location information of an unconfigured area # 2 1 8 7, the location information of an unconfigured area # 3 188, and an unconfigured area # 4 189). Register the location information of the unallocated area in the unallocated space registration 1 5 5 so that the location information of the latest file structure area 1 3 1 outside and closest to its unallocated area is registered in the unallocated space registration 1 5 5 And then register the latest file structure area 1 3 1 outside and the location information of the second unconfigured area close to it in the second most internal of the unallocated space registration 1 5 5 so that when the latest Information is moved from one inside to the other of the disc while the latest information is recorded. When the position information of the outermost unconfigured area is registered in the unconfigured space registration 1 5 5, the position information of these unconfigured areas is registered in the unconfigured space registration 1 5 5, so that Register the position information of the innermost unconfigured area in the second innermost portion of the unconfigured space registration 155, and then register the position information of the second innermost unconfigured area in the unconfigured space registration 1 5 5 Its next most inner. In the example shown in FIG. 1, the unallocated area # 1 (1 2 4) is the area closest to the latest file structure area 1 3 1. If so, the position information 186 of the unallocated area # 1 (124) is registered in the unallocated space registration 155 as the first position information. Next, the position information 187 of the unallocated area # 2 (1 2 5) at the end of the magnetic volume space is registered in the unallocated space registration 155 as the second position information. Next, the position information 1 8 8 of the innermost unallocated area # 3 (1 2 1) in the magnetic volume space is registered in the unallocated space registration 1 5 5 as the third position information. Finally, the position information 189 of the unallocated area # 4 (1 2 2) is registered in the unallocated space registration 155 as the fourth position information. In this way, the position information of these unconfigured areas is determined by unconfigured area # 1 (124), unconfigured area # 2 (125), unconfigured area # 3 (12 1), and unconfigured area # 4 (122). The order is registered in unconfigured space registration 1 5 5. The data can be recorded to the unallocated space registration 1 5 5 in the order of “the unallocated areas are registered in the above-mentioned order” and “5. "Allocation area" to record data while moving the latest file structure area on the disc. As a result, it is possible to avoid rewriting the data in a special area in a concentrated manner, thereby preventing the occurrence of flaws and the destruction of the data.

When deleting or editing data recorded on the disc, an area that is still in use will become unnecessary. The position information of the area which becomes unnecessary is registered in the unallocated space registration 1 5 as the position information of a new unallocated area. The position information of the newly registered unallocated area to be located in the unallocated space registration 15 is calculated based on the position information of the unallocated area registered in the unallocated space registration 1 5 5. As a result, the position information of the new unallocated area is inserted into an appropriate position in the unallocated space 1 5 5.

In this example, the position information of an unconfigured area is registered to the position in the unconfigured space registration 1 5 5 based on the positions of the unconfigured areas in the magnetic volume space. Alternatively, when an area becomes unnecessary due to data deletion, the position information of the area that becomes unnecessary may be registered at the end of the unconfigured space registration 1 5 5 as a new unconfigured area 'S location. Or it can be determined that the position information of an unallocated area is registered to the position in the unallocated space registration 1 5 according to "the time when the area becomes unnecessary and it returns to a new unallocated area". The method can also avoid overwriting data in a special area. The device for recording data from an inside to an outside according to the present invention is also applicable to a write-once type disk. In FIG. 8, there is illustrated that Examples of control files that require data reliability. Alternatively, multiple control files can be recorded on the disc. If so, the control files can be recorded in the basic file structure area or the AV file area. When these When the control file is small or when the total number of control files -35-1235361 (3,) is small, it is better to record the control files in the basic file structure area. This is because when the control files are recorded in The basic file structure area will be easier to access. When the control files are large or when the total number of control files is large, it is better to record the control files. The AV file area. This is because the latest file structure area can be kept small in this way. It will be apparent that when the control files and the file registration of the control files are recorded in the AV file area, When updating such control files, the data can be avoided from being overwritten in a special area. According to the recording position information indicating the next recording position (designated by the registration sector number), the loop recording system is executed in a certain direction. Possibly. Obtain the location information of the recordable area from the space management structure. 1.6 Data structure of the record information section Figure 9 illustrates a representative data structure of the record information section 1 1 1. In the example shown, the record information section 11 includes a counting unit and 250 registration units. The counting unit includes 10 counting blocks. For example, each of these counting blocks is shaped into a minimum record. Cell "ECC (Error Checking and Correction) Block". The `` information '' indicating which of the 250 registration units is a valid registration unit (for example, a registration block in which the valid registration magnetic zone number is recorded and the identification code Γ of the registration unit to which it belongs is recorded in In one of the counting blocks. Use the counting unit to search for a valid registration unit among the 250 registration units. Using this counting unit will allow "only reading a valid registration unit to get the latest Registered Sector -36-Send it _continued 1235361 (32) number ", without reading all such registration units. When the ID of the valid registration unit is changed, rewrite each count area If so, the number of rewrites of the count block is very small compared to the number of rewrites of the registered block.

From the leading count block (first count block), 10 count blocks contained in the count unit are sequentially used. A count block is used repeatedly until the count block becomes unrecordable. For example, the count block becomes unrecordable because the number of data rewrites exceeds the number of repeatable reads and writes; and the count block is in a defective state due to dust adhesion, etc. When the first count block becomes unrecordable, a second count block is used. When the second count block becomes unrecordable, a third count block is used. Each count block is rewritten in this manner until the count block becomes unrecordable. When the count block becomes unrecordable, the next count block is used. If so, because the data is rewritten less often, the count blocks can be searched at a faster speed.

Each of these registration units from the first to the 250th registration unit includes 10 registration blocks. Each of these registered blocks is formed into a minimum recording unit '' E C C block '. Each of these registration blocks includes an area for recording a version number (version information) and an area for recording a registration magnetic area number (index information), where the version number indicates a The version and the registration sector number indicate the end of the latest file structure area. Whenever the information is recorded in the latest file structure area, the edition -37-send confirmation _ Jibu 1235361 (33) This number and the registration sector number are recorded. Recorded in such a section from a registration unit One of the registration blocks selected from one to tenth registration blocks. Every time data is recorded in the latest file structure area, the registration block that records the version number and the registered magnetic sector number is changed. For example, when the data is recorded in the latest file structure area for the first time, the version number and the registration magnetic zone number are recorded in the first registration block; and when the data is recorded in the second When it is in the latest file structure area, the version number and the registration magnetic field number are recorded in the second registration block. In this way, the version number and the registration sector number are sequentially recorded in a registration block (from the first to the tenth registration block). After recording the version number and the registration sector number in the 10th registration block, the version number and the registration sector number are again recorded in the first registration block (overwriting the first A registration block). Then, the version number and the registration magnetic zone number are sequentially recorded in a registration block (from the first to the tenth registration block) (overwriting the data in each registration block) . By sequentially recording the '1¾ version number and the registration sector number in each of these registration blocks, it is possible to prevent the data from being overwritten in a special registration block. The position indicated by the registration sector number (indicator information) is not restricted to the end of the latest file structure area. The location indicated by the registration sector number (indicator information) can be any location (such as a predetermined location) in any area on the disc 2 (such as the second information recording area). The second information recording area may be an area in which data can be recorded by "Sequential Loop Record -38-1235361 (34) Posting Conversation and Recording"). In this example, the data is repeatedly recorded sequentially in each of the 250 registration units. That is, each of these registration units is the first information recording area in which data can be recorded by sequential loop recording. Repeatedly recording data in this way in each of the plurality of divided areas can improve the reliability of all such areas and increase the speed of reading each area.

The latest registered block is managed such that the largest version number is in the registration unit to which the latest registered block belongs. The maximum version number indicates the latest version information. Use the registered sector number (index information) corresponding to the largest version number (latest version information) as the valid registered sector number (valid index information). In the example shown in FIG. 9, the third registration block of the version number (3) is the latest registration block. If the registration unit includes 10 registration blocks in this way, the latest registration block can be identified by reading only the data in the 10 registration blocks at most.

When one or more registration blocks in a registration unit become unusable, the next registration unit is used. For example, when one or more of the registration blocks in the first registration unit becomes unusable (or when the version number of the registration block reaches a value in the first registration unit), the Two registration units. The counting unit identifies the valid registration unit. If so, it is not necessary to search all 250 of these registration units when the valid registration unit is to be identified. The recording record information section can be improved by providing one -39-1235361 (35) reserved record information sections in the augmented record information section 1 12 shown in FIG. A copy of the information in this paragraph 1 1 1 is recorded. When the registration sector number is read in a recording information section 1 1 1 due to a reading, the registration sector number is read in a recording information section 1 1 2. It is not necessary to mention 1 1 1 in the leading area and the following area. The sector 1 1 1 may be recorded, for example, inside a leading area. Alternatively, it is possible to have 1 M section 1 1 in the magnetic coil structure area. In these cases, the effect of preventing the special magnetic domain is provided. This is because when performing a slide instruction to indicate that the tail of the area where the registration sector number is recorded does not limit the total number of counted blocks to 10. This is 1 or any number greater than 1. The registration block was not placed. The total number of counted blocks can also be 1 or any number greater than the total number of registered units is not limited to 250. Can be 1 or any number greater than 1. When the registration form is used, the counting unit can be omitted because there is no need to search for the unit. The record information section can be constructed into only RMB. When, for example, the total number of registered blocks is large enough, it may be constructed to include only one registered unit. The recording unit in the recording information section may be a 4 recording unit limited to one ECC block. The disc may contain identification information pre-recorded thereon, which indicates that the recording information section is allocated to the first release of the disc, and so on, the reliable recording of the I * section 1 1 1 in the recording information area is incorrect and cannot be self If you have, you can rewrite the information recorded in the information provided in the field of the information record section of the augmented record for centralized rewriting in the one-loop record. The total number of count blocks can be limited to a number of 101. The total number of registration units. The total number of yuan is equal to 1. The valid registration form contains a registration form that records the information area of 3 magnetic areas' and the remote identification information does not refer to a predetermined area. 1235361 (36) domain. When the disc is shipped, the identification information will ensure the high reliability of the disc, which limits the number of times data can be rewritten onto the disc. This is because the data can be repeatedly recorded sequentially by using the record information section to compensate for the limitation of the number of times the data is rewritten.

A once-only disk can be considered as a disk with a limit of zero data rewrites. Using the above-mentioned record information section will allow rapid identification of the valid registration unit and the valid registration block recorded in the valid registration unit, even when the data is rewritten more frequently. When the data is rewritten more times, so that all the registration units in the record information section are used, it may be continued by configuring a part of the expanded record information section into a record information section Information rewriting.

It is also possible to provide a write-once type disk with a more appropriate data structure by increasing the total number of registered blocks in a registration unit or by increasing the total number of counting blocks in a counting unit. . For example, when the total number of counting blocks in the counting unit is equal to the total number of registration units, the number of updates of the registration unit may be updated to update the counting block. When the total number of counted blocks in the counting unit is greater than the total number of registered units, the next counted block can still be used even if the counted block cannot be updated because of a defective block, etc. The data can be repeatedly recorded in the counting unit in order to prevent the data from being overwritten in a special counting block of the counting unit. That is, the counting unit is an example of the third information recording area in which data can be recorded by sequential loop recording. If so, each counting block in the counting unit contains "a version number (version-41-1235361 (37) this information Γ and" an identification code of the registration unit (identifying the above) The registration block is the same. The latest count block is managed and the maximum version number is edited. The maximum version number indicates that the identification of the latest version asset to the maximum version number (latest version information) is additionally used as the valid registration. Valid ID of the unit (Valid ID 1 by repeatedly recording data in the counting slip unit repeatedly to keep the old information in the counting block and. If so, pre-updated information (file ) So that the information (file) can be used as backup information. The above-mentioned recording method is applicable to a write-once type rewritable and rewritable disk. Therefore, a common use for a rewritable type of disk The recording method may be that for the optical disc that limits the number of times of data rewriting, instead of recording, the registration block in the registration unit is set until the registration block changes Until it becomes unrecordable, the time that this unit reads the data. For example, the number of times that the registered block exceeds the number of times that it can be read and written repeatedly, and the registered block becomes unsuitable due to dust adhesion, etc. And is under. When the registered block becomes unrecordable, the block is remembered. By repeatedly using a counting block, the block becomes unrecordable. At the same time, by repeatedly refining the block, until Until the registration block becomes unrecordable, the time required for the unit to read the data will also shorten the time when the registration form sends out the information on the continuation page) ", just like the number in the counting form. Using the relative J code (identification Information) Information). Yuanhe each registered these registration blocks on the disc, a disc-type disk and a read-write disc and only used. Performing a sequential loop into `` available '', shortening since Logging is recordable because of data rewriting; and a defective status uses the next log up to the counting area and a registration area to reduce the time required to read the data from the counter. • 42-1235361 (38) The time for concealing pages. File Play FIG. 7 illustrates a floor plan playback processing program for playing a file recorded on the disc 2 35. The file playback processing is performed by the recording and playback device of the information 1 shown in FIG. 2. It will be described later. The steps shown in Fig. 7 are described in detail. In the following example, an AV file (AV file-d) 158 is played from the optical disc 2 3 5 having the data structure shown in Fig. 1.

By "Delete the AV file (AV file-b) in the disc 2 3 5 with the data structure shown in Fig. 6" and "Record an AV file (AV file-c) and an AV file (AV file- d) · 'to obtain the optical disc 23 5 shown in FIG. 1. (S701) When it is detected that a disc is inserted into the disc drive device 205, the drive control area 2 3 1 designates the first count block 1 7 1 of the counting unit 1 4 1 in the recording information section 1 1 1 position. (S702) The drive control area 2 3 1 determines whether the designated counting block in the counting unit 1 4 1 is in a state of no recording. When "yes," then

The process proceeds to step (S704); and when "NO", the process proceeds to step (S703). (S703) The drive control area 231 specifies the position of the next counting block in the counting unit 141. (S 7 0 4) The drive control area 2 3 1 obtains an identification code (identification information) of a registered block from the last one of the counting blocks that are not in an unrecorded state. . (S 7 0 5) The drive control area 2 3 1 starts a playback job from the leading registration block in the registration unit specified by the registration unit identification code, so -43-(39) (39) 1235361 says Continue buying: ^ %% ¾¾¾¾¾¾¾ Get a version number (version information). (S 7 0 6) The drive control area 2 3 i specifies the position of the next registered block in the designated registration unit. (S707) The drive control area 231 executes a playback job from the designated registration block. When the registration block designated by the playback job is in an unrecorded state, or when the version recorded in the registration block is edited less than the previously obtained version number, then the process proceeds to step (S709 ). Otherwise, the process proceeds to step (S708). (S 70 8) The drive control area 23 1 specifies the position of the next registered block in the designated registration unit. (S 70 9) The drive control area 23 1 obtains a registration sector number recorded in the latest registration area block, and stores the registration sector number in the recording information sector memory 273. For example, the drive control area 23 1 described in steps (s 7 〇) to (S709) is achieved by a control program built in the drive control area 23 1 as an information recording and playback device 2 7 2. Assignment. (S7 10) The system control area 20 1 obtains the registered sector number stored in the record information section memory 2 7 3 of the optical disc drive device 2 5 as information indicating the end position of the latest file structure area ( Metric Information). The system control area 2 0 1 instructs the optical disc drive 2 0 5 to play a VATICB 57 recorded at the end of the latest file structure area. For example, by executing a control program built in the system control area 201 as the V AT structure playback device 2 1 5, the operation of the system control area 20 1 described above is achieved. Optical disc drive 2 Reads the -44-1235361 (40) recorded at the end of the latest file structure area

VATICB 157 and VATiCB 57 are stored in the VAT structure memory 2 2 2 of the memory circuit 202.

Then the 'system technology area 201 decodes the position information of the VAT contained in the read vaTICB; follows a control procedure similar to the VATICB in order to read a VAT recorded in the VAT structure area 108 156; and VAT 156 is stored in vat structure memory 222 of memory circuit 202. (S7 1 1) System control area 2 〇 丨 Read a file registration (root directory) from a file set description item 5 2 and 5 4 and a root directory 5 3, and use this in step (S7) at the same time. The Vat obtained in) converts the virtual address into a logical address. The system control area 20 1 also reads one file registration (AVDir) 151 and one AV directory (AVDir) 150 recorded in the areas recorded in the file registration (root directory) 1 5 4 and the root directory 1 5 3, and then follows Sequentially read a file log (data file) 14 9 and a control file (data file) 1 4 8. If so, obtain the record location and related information of these a V files. For example, by executing a control program built in the system control area 201 as the basic file structure playback device 2 61, the operation of the system control area 201 is achieved. (S7 12) Finally, the system control area 2 reads a file registration (AV file-d) 159 and an AV file (AV file-d) 158 to complete the file playback operation. For example, by executing a control program built in the system control area 2 01 as the file playback device 2 16, the operation of the system control area 2 01 is achieved. In order to prevent the data from becoming unreadable due to a reading error during playback, sighing that it was read by the 1235361 (.) Method, a copy of the material can be recorded in another area. The latest file structure area moved by sequential recording can be doubled, and the location information of the doubled latest file structure area can be specified in the record information section. For example, as shown in FIG. 10, a main registration sector area 2103 and a main latest sector structure area 2 107 may be designated according to a main registration sector number 2151 and a reserved registration sector number 2152, of which the main registration sector The numbers 2 15 1 and the reserved registration number 2152 are recorded in the registration blocks recorded in the registration unit recorded in a reserved record information section 2101 and a main record information section 2102, respectively. Data may not be played back due to scratches or dust caused by the check-type sequential recording. The main latest file structure area 2107 and the most recent file structure area 2103 can be provided in the magnetic volume space, and their location information can be registered in the leading area as the main registration magnetic area number 2 15 1 and the reservation registration The sector number is 2152 so that the latest file can still be read in this case. If so, the reliability of data playback has been improved. The information to be recorded in the retention latest file structure area 2103 is basically the retention information of the information to be recorded in the main latest file structure area 2 107. A VAT 2 145 to be recorded in a VAT structure area 21 10 is a correspondence table of the virtual address and logical address of the latest file structure recorded in the main latest file structure area 2107. In contrast, a VAT 2135 to be recorded in a VAT structure area 2106 is a correspondence table of the virtual address and logical address of the latest file structure of the record in the latest file structure area 2103. -46-Invention Description Continued 1235361 (42)

The position information of the main latest file structure area 2 107 and the position information of the most recent file structure area 2 103 can be registered in the main record information section 2102 and the hold record information section 2101 of the leading area as the main registration magnetic area, respectively. Number 2151 and reserved registration number 2152. If so, the reserved record information section 2 101 is an area for recording the reserved information of the information registered in the main record information section 2 102. The structure and apparatus using these main or retained recording information sections are similar to those of the recording information section shown in the use example 1. The location information of the area holding the latest file structure can be specified by a shift address in the main registration sector number. The displacement address can be specified as, for example, the main registration sector number-256, the main registration sector number-5 1 2, the main registration sector number + 2 5 6, or the main registration sector number + 512 . The displacement value can be registered in the information recording section.

Even if the recorded information section is provided in the magnetic volume space instead of the leading area, the effect provided by the present invention is not affected at all. For example, the registration volume number can be recorded in the volume space (such as the volume structure area 1 0 1). If so, the effect is substantially the same as the effect produced by recording the registration sector number in the leading area. Recording position information (such as the registration sector number) indicating the start position of the next record allows data to be recorded repeatedly in a certain direction, so that the area of the rewritten data is scattered throughout the information record of the information recording medium Area. The retained information of the information recorded in the main record information section can be registered in the main record information section 2 102 and the retained record information section -47- 1235361 (43) 2 10 1 respectively. If so, use auditing records to record the count block to avoid defective areas. Therefore, the defective area in the main record ^ and the reserved record information section 2101 has a block number or a registered block number. When the duplicate information is recorded in the reserved record information section 21 or the registration block, the counting block or the registration block may mainly record the counting block or the registration area of the information section 2 1 02. The phase check in the record information section 2 1 0 1 enables recording to be performed even in a defective state. In this example, the recorded information in the Keep Latest File Structure area is the copy information of the main latest file structure. To narrow down, you can keep only the files updated in the previous recording time in the latest file structure area. When the resources cannot be read from the main area, a backup of the data can be obtained by using the main latest file structure before the latest file is retained. "The version number identifies the previous registration block" and "the registration sector number in the use block" 'to obtain the previous main structure. As described in FIG. 10, the maximum number of recordings in the magnetic volume space is doubled. When the doubling of the latest file structure is located in the leading area, the robustness of the file structure area can be improved during sequential recording. The file structure area is indispensable when recording and playing the file. , And the number of times it was limited to that information recording medium. By making sure that the data is _continued to buy or block ^ message section 2102 different counts 0 1 counts the same as it is recorded in the block. Such as ί-style records. That is, the information in the domain is short. The record structure is recorded in the new file structure and the first record. The new file structure is based on the latest file recorded in the registration. (-) In the record information section of the location information of the latest file structure area assigned to the multiplier to improve the reliability of the disk's playback without consideration There is a risk that it may not be played due to scratches or dust. It will be apparent that the latest file structure area and the registration sector number are applicable to double, triple, and other multiple types. In these ECMA 167 standards, The file registration of the AV file is defined as part of the file structure. In this example, to simplify the description, the file registration of the AV file is recorded in the AV file area. When no AV file is recorded on an information recording medium At this time, a control file can be recorded in the AV file area. However, the effectiveness of the present invention is still not affected. If so, the control file and its file The structure is sequentially recorded in the magnetic volume space. In this example, a file structure using the VAT structure is recorded in the latest file structure area. Other file systems (such as a FAT (File Allocation Table) file) System, ..., etc.), a file structure is recorded in the latest file structure area specified by the registration sector number. As far as using the registration sector number recorded in the record information section, even when a different In the file structure of the VAT structure, it still provides the function of `` avoiding data overwriting on a single disk (which limits the number of data overwriting) ''. In this example, when a disk is inserted, the system records a control file in the basic file structure area to identify the information recorded in the plurality of AV files. When it is only necessary to identify the file recorded on the disk, the control file and its file registration need not be recorded in the basic file -49- 1235361 (,) structure area. As a result, the basic file structure area is smaller, and the recording time is shortened as such. When the basic file structure area is recorded in an ECC block serving as the minimum read unit, the drive device fetches data only once. In this way, an information recording medium according to the present invention moves the data to be updated or recorded including the latest file structure area from an inside to an outside. Therefore, the data is prevented from being damaged or defective due to centralized rewriting, and the reliability of the data can be improved. 2. Example 2 In Example 2, "a method for sequentially recording an AV file in the pre-configured AV file area of the magnetic volume space" and π-a method of recording in the latest file structure area will be explained. The defect management device of the information · '. It is necessary to continuously record the AV data to be recorded in the AV file area at any time, if it is recorded without checking. It requires file management information (such as the file collection description item) and a The control file is reliable, and if it is recorded by checking to ensure the reliability of the data during recording. Generally speaking, the data size of an AV file is large; and the file size of a control file or file management information But it is very small. If so, AV materials and non-AV materials have different characteristics. An example that separates "an area for recording AV material" from "an area for non-AV material" will be explained. When a non-configured area is managed in the form of a table as in Example 1, the order in which the management information is registered in the non-configured areas is executed sequentially. Records. In Example 2, an unconfigured area is managed using an improved bitmap recorded in the space management structure area, and -50- August of the Invention Continued Page 1235361 (46) Sequential recording is performed in the AV file area. In the following description, the recording is recorded on the information recording medium as a descriptive item, an indicator, etc. of a magnetic volume file structure, which has a standard according to ECMA167 or UDF The defined data structure; unless otherwise, it will not be described in detail. 2.1 Data structure of the disc Figure 1 1 illustrates a representative data structure of the disc 2 35. A fixed position in the magnetic volume space is pre-configured A magnetic volume structure area 1 0, a spare file structure area 1 3 0 3, and an AV file area 1 3 0 8. The spare file structure area 1 3 0 3 contains a space management in a part of the latest file structure area. Structure area 1 3 0 6. To record a modified bit map in the space management structure area. A bit map is a description of a unit (such as a magnetic area or Each ECC block) maps the recording status of each of its areas. 0 indicates a non-recorded status; 1 indicates a recorded status. A set of bits that describe the recording status of all the magnetic areas means one bit. Meta mapping. In Example 2, a bit mapping describes the recording status of a unit. The advantage of managing an unconfigured area by a bit mapping is that it uses a bit in each managed area to designate these unmanaged areas. The area is configured, so the size of the bitmap is fixed. A "unit" is a unit that contains one or more magnetic areas to manage records. In this example, a unit contains approximately 5000 magnetic fields. The leading area is provided with a record information section 1 1 1. The record information section 1 1 1 contains a spare designation information area 1 3 0 2 of which the spare designation information -51 · sighs said that the continuation page 1235361 (47) the news section 1 3 0 2 contains a spare unit number 1 3 1 0 and spare area address information 13 1 1. In the spare designated information area, a spare area 1 3 07 or other unit of the spare file structure area 1 3 0 replaces a newest file structure area 1 3 04. If so, the replacement will prevent the entire media from becoming unrecordable when the data set is rewritten in the latest file structure area 1 03 of the spare file structure area 1 03, or when the entire area becomes unrecordable. As a result, data can be recorded in this latest file structure area. 2.2 File Record Processing Figure 13 illustrates a file record processing procedure for recording a file on a disc 2 35. The file recording process is performed by the information recording and playback device shown in the figure 2. The steps shown in Figure 13 will be described in detail below. (S 150 1) The system control area 2 0 1 obtains a starting unit number 1 3 3 0 from the front end of the modified bit map 1 3 1 3, wherein the modified bit map 13 13 has been read in Space management structure memory 253. For example, by executing a control program built in the system control area 201 as the space management structure recording device 2 51, the operation of the system control area 201 is achieved. (S 1502) The system control area 20 1 instructs the optical disc drive device 205 to sequentially record the A V file (AV file-d) 146 from the unit # 40 designated by the start unit number 1 3 3 0. The operation of the system control area 201 is achieved, for example, by executing a control program built in the system control area 201 as the file recording device 2 1 3. (S 1 5 03) The system control area 201 updates the file structure containing the recorded AV file (AV file-d) and its management information, and commands the CD-ROM drive device -52- 2 05 Record the updated file structure in the latest file structure area 1 3 0 4. For example, by executing a control program built in the system control area 201 as the basic file structure recording device 26, the operation of the system control area 201 is achieved. At this moment, when the latest file structure area 1 3 04 of the spare file structure area 1 3 04 becomes unrecordable due to overwriting, scratching, or dust in the data center, and then causes the optical disc drive 2 0 5 to report another In the case of a recording error, the system control area 2101 updates the basic file structure in order to change the recording position, and commands `` the recording should be performed in the spare area 1307 ''. When the spare area 1307 is heavy due to data concentration When writing, scratching, or dust becomes unrecordable, and then causes the optical disc drive device 2 to report a recording error, the system control area 2 01 command "舄 records a basic file structure area, where the Change the recording position to Unit # 5 6. In this way, unit # 56 can be used as a spare file structure area, where unit # 56 is the next recording start unit for sequential recording in the AV file area 1308. In this way, if a recording error occurs when data is recorded in the latest file structure area, the data recorded in the latest file structure area will be updated, and the updated data will be recorded in an unrecorded spare area in. When there is no unrecorded area in the spare area, use the starting unit number to allocate a spare file structure area to an unallocated unit, and update the data recorded in the latest file structure area and the updated data Recorded at the front of this spare file structure area. When the spare file structure area is allocated to the unallocated unit, a spare area whose size has been determined is arranged in an unrecorded state -53-1235361 (49). Therefore, even if a recording error occurs while data is being recorded in the latest file structure area, backup recording is still possible. The drive control area 2 3 2 commands the recording and playback device 2 3 4 to record this basic file structure in unit # 56. When the recording is completed, "5 6" is recorded in a spare unit number 1 4 1 0 of the recording information section 1 1 1 of the leading area, and the address information of the latest file structure area is recorded in The spare area address information is 1 4 1 1. Then, the drive control area 2 3 1 notifies the system control area 2 0 1 " The process is completed ''. (S 1 5 04) The system control area 2 0 1 produces an improvement The bit map 1 4 1 2 is used to reflect the state of an unallocated area of the disk and the modified bit map 1 4 1 2 is recorded in a space management structure area 1 4 0 3. For example, borrow The above-mentioned operation of the system control area 2 01 is performed by executing a control program built in the system control area 2 01 as the space management structure recording device 2 51. At this moment, the unit # 5 7 is registered as the improved one The starting unit number of the bit map front end, where unit # 5 7 indicates the first unconfigured area behind the unit of the record. With this processing, the bits of unit # 40 ~ # 56 become " 1 " ( Indicates "has a record") where these bits Indicate the recording status of the units in which data is recorded. Figure 12 illustrates the data recorded on the disc 2 35 after the file recording process is performed on the disc 2 3 5 whose data structure is as shown in FIG. 11. In this example, the sequential recording of the second cycle is performed from the inside to the outside of the AV file area. Rewriting on a restricted material 〇4- 1235361 Posting instructions continued (50) times In the information recording medium, the starting position of the recording is designated by a starting unit number. Therefore, sequential recording can be repeatedly performed in the AV file area (from an inside to an outside of the disc).

Instead, the start position of the next record can be specified by an address instead of a start unit number. Rather than using a starting unit number, when the starting position of the next record is specified by an address, the starting position of the record can be specified in more detail. Instead, the end position of the previous record can be specified instead of the start position of the next i-record. In this example, the unallocated areas of the recordable AV files are designated on a unit-by-unit basis; and the areas of the AV files are designated on a logical sector basis. For simplicity, the area where such AV files are recorded can also be specified on a unit-by-unit basis. In this example, only these AV files are recorded in the AV file area. As described in Example 1, a file registration of the AV file may also be recorded in the AV file area. If the size of the control file is very large, or if the total number of control files is very large, the control file and its file registration may be recorded in the AV file area. In this way, when such control files are updated, the data is prevented from being overwritten in a special area. If data is recorded in the magnetic volume structure area and the latest file structure area, check-type recording is performed; if data is recorded in the AV file area, non-check-type recording is performed. "_Checked record" means a type of recording device "that confirms readable data after the record has been performed"; "No check-type record" means a type of "after the record has been performed without confirmation Talk about continuation page 1235361 (51) Read data "recording device. In this example, the system control area 20 1 manages the latest file structure area after the replacement. In a drive control area 2 3 1 manages the backup The system of the area can be managed by a system that means "linear replacement". "Linear replacement" means a system in which the drive control area manages the logical bits designated by the system control area Correspondence between "address information" and "actual location information of the address of the actual recorded data". As far as the system is concerned, it does not by accessing the logical address of the instruction,

It is played by reading data from the corresponding actual position. In the system, the control area of the system does not need to update the recording position information of the basic file structure according to the replacement. When the two-stage replacement process is performed (including "replace with a spare area" and "allocate a spare file structure area to a unit), even a medium with a clear file structure area capacity or an AV file area capacity has its data When the number of rewrites suddenly increases, recording and playback on the medium can continue.

2.3 File playback processing Figure 14 illustrates a file playback processing procedure for playing a file recorded on a disc 2 3 5. The file playback processing is performed by the information recording and playback device shown in the figure 2. The steps shown in FIG. 14 will be detailed later. In the following example, an AV file (AV file-d) 158 is played from a disc 2 3 5 whose data structure is as shown in FIG. 12. (S1 601) When an optical disc is inserted into the optical disc drive device 205, the drive control area 2 3 1 will be from the spare designated information area of the recording information section -56- Jieeryuan 1235361 (52) 1 3 Ο 2 Read a spare unit number 1 4 1 0 and spare area address information 1 4 1 1 and inform the system control area 2 0 1 of `` spare unit number 1 4 1 0 '' and '· spare area address information 1 4 1 1 ". The above-mentioned operation of the system control area 201 is performed, for example, by executing a control program built in the system control area 201 as the information recording and playback device 272. The system control area 201 determines whether the read spare unit number 14 10 is 0 or 1. When it is 0, the process proceeds to step (S1603). Otherwise, the process proceeds to step (S1602). (S 1602) System control area 201 plays a basic file structure area from a basic file structure area of the latest file structure area recorded in a unit with the specified unit number based on the spare unit number and the spare area address information. File structure. In the example shown in FIG. 12, the spare unit number 1410 is 56. If so, a basic file structure is read from a basic file structure area 1402 of the latest file structure area 140 1 recorded in cell # 5 6. (S I 603) The system control area 201 plays a basic file structure in a basic file structure area of the latest file structure area in a pre-configured standby file structure area based on the backup address information. In the example shown in FIG. 11, the spare unit number 1410 is 0. If so, a basic file structure is read from a basic file structure area 1305 of the latest file structure area 1304 recorded in the spare file structure area 1303. For example, by executing a control program (S 1602) and -57- (53) 5361 (S1660) which are built in the system control area 201 as a basic file structure playback device 262 < < System control area 2 0 1 for operation. (Sl60〇4) # This is why the basic file structure is decoded by the "system area 2", and broadcasted by%, the required "" Jianming Xuan, AV case (AV file-d) 158. For example, by executing an operation in the j area 201 as a control program of the file playback device 216 $ system control area 201. Generally, the AV files such as II and Yu ° are larger than the control data. • Therefore, in this example, # c ^ θ manages these AV files on a unit-by-unit basis. If not, you can use a unit number instead of a logical sector number to easily specify the recording position information of an AV file. In this example, the unconfigured areas are registered in the bitmap in the order of one inside to one outside of the disc. If so, the next record position can be specified with a start unit number to perform sequential loop recording. By using a method as shown in Example 1 to manage the unallocated area, the unallocated area is placed from the inside of the disc to the outside in the order #left in the table, and a registration sector number Specify the starting position of the next sequence record for recording. In Example 2, the structural area of the spare building case is pre-arranged in the magnetic volume, so the '' bei material 'is rewritten in the far latest building case structure. However, the space τ μ 々 allows the data record to be specified in the spare designated information area of each record information section.

Coffee in different positions. Result 'prevents the entire media from becoming unrecordable on a 1U. The starting position of the AV file area can be obtained by using the improved bit mapping in the space management structure to map the starting unit number of a record provided in the structure domain. This allows sequential recording of these A-V files -58-title page 1235361 (54), while avoiding centralized data rewriting. If the starting unit number is registered at the front of the space management structure, recording can be started from the recording start position immediately after obtaining the space management structure. In Example 1, data are sequentially recorded in the latest file structure area. In Example 2, whenever the data is updated, the data is rewritten into the latest file structure area. As described in Example 1, using "the blank area information recorded in the space management structure area" and "alternate address information indicating the location of the latest file structure area", the latest file structure area is sequentially And repeatedly recorded in the backup file structure area. For example, the following methods can be used to record and update the data. From one position following the position of the area where the latest file structure area is arranged (that is, indicated by the indicator information) Position), searching for an unallocated area in a certain direction (for example, from the inside to the outside of the disk), searching all the way to the end of the spare file structure area. According to the search result, configure the area, And the data of the latest file structure area is recorded in the configured area. If the latest file structure area is recorded at the end of the backup file structure area, it starts from the front of the backup file structure area and starts with a certain one. Search for an unconfigured area, and record the data of the latest file structure area in It can be understood that the spare file structure area is constructed so that another area (such as the latest file structure area) can be allocated to a part of the spare file structure area. The spare file structure area will be allocated to the Part of the different areas (such as the latest file structure area) can be moved in the backup file structure area. If so, it can be recorded repeatedly in a certain direction As a result, the latest file structure area is scattered over the entire backup file structure area. In Example 2, sequential loop recording can be performed in both the AV file area and the backup file structure area. If so, the centralized data rewriting is avoided In any special area on the entire disc, you can improve the reliability of data and improve the readability of a desired file by dividing an area into multiple areas and performing sequential loop recording in each of these divided areas. Speed 3. Example 3 In Example 3, one is used to manage an archive record location and an unconfigured A table for the location of the area (such as a FAT file system applied to a hard disk ... etc.) records the AV files in the AV file area in sequence. 3 When constructing a system compatible with a hard disk In this case, a FAT file system can be referred to the disc by a file system to process the hard disk and the disc. In the following description, it is recorded on the information recording medium as a description item of a magnetic volume file structure , An indicator ... etc. all have a data structure defined in accordance with ECMA 167 or UDF standards; unless otherwise, it will not be described in detail. 3.1 Data structure of this disc Figure 1 5 Description disc 2 3 5 A representative data structure of the. The volume volume contains a system area 17 (H, a latest file structure area 1702, and an AV file structure area 1703. • 60- Exclamation 嚷 Continued 1235361 (56) The latest file structure area 1702 contains a FAT (File Allocation Table) area 1 7 0 4, a root E record area 1 7 0 5, an AV directory area 1 7 0 6 , And a data file area 1707. A FAT is recorded in the FAT area 1704, where the FAT contains "link information of the directory recording position and the file recording position" and "recording state information of the magnetic clusters".

The F A T is a table in which magnetic error recording information is recorded, wherein the magnetic cluster recording information includes recording information of each magnetic cluster. The total number of recorded magnetic clusters corresponds to the total number of magnetic clusters. The start cluster number of the directory and the start cluster number of the archive are registered in a directory entry recorded in the root directory area 1705 and an AV directory area 1706. In the example shown in FIG. 15, a directory registration (AV file -a) 1 7 1 3 contains an AV file (AV file-a) 144 of the first cluster number 1. The FAT link information includes "Cluster # 1" which is an initial magnetic cluster of the AV file (AV file-a) and "Cluster number # 2 of the next magnetic cluster registered there." In this way , Follow the link information to play the AV file (AV file-a). In the "value" area of the link information, " EOF (End of File) " indicates the end of the file (eg FF8 (ten (Hexadecimal)). A magnetic cluster is a unit that contains one or more magnetic areas for record management. In this example, a magnetic cluster contains approximately 500 magnetic areas. 3.2 File Record Processing Figure 1 6 describes a file recording processing program for recording a file on a disc 2 35. The file recording processing is performed by the information recording and playback device shown in FIG. 2. The details of FIG. 16 will be described later. The steps are shown in the following. -61-Sending instructions to continue to buy 1235361 (57) (S 1 80 1) System control area 2 0 1 reads a FAT from the latest file structure area 1 702 and the front FAT area 1 704; Searching for a magnetic cluster number whose mark is the starting point information; and the magnetic cluster number from the mark Initially, the information of the unconfigured area is sequentially obtained in a different power order. For example, the above-mentioned system control area 2 is achieved by executing a control program built in the system control area 2 01 as a space management structure recording device 2 51. Operation of 0 1. (S 1 802) System control area 2 0 1 Records AV files sequentially from the specified starting point magnetic cluster. For example, by executing a built-in system control area 2 0 1 as a file The control program of the recording device 2 1 3 achieves the operation of the system control area 2 0 1 described above. (S 1 803) The system control area 2 0 1 will contain the AV directory area of the recorded AV file information, the root directory area, etc. The data file and the FAT area are recorded in the latest file structure area. The magnetic error information is updated in the FAT recorded at that point, where the magnetic error information contains the link information and starting point of the recorded files Information. For example, in Figure 15 and π, the data structure after recording the AV file (AV file-c) 1 4 6 is displayed. The next recording start point is magnetic cluster # 5 6. Therefore, "'1" is registered as the starting point information of FAT 17 1 0 and its magnetic error # 5 6. For example, by executing a control program built in the system control area 201 as the basic file structure recording device 2 61, the operation of the system control area 201 is achieved. In this example, the sequential recording of the second cycle is explained from one inside to one outside of the AV file area. In an information recording medium that restricts the number of times of data rewriting, the sequential loop -62-1235361 (58) recording is performed in a similar manner to performing the first loop and subsequent loop sequential recording in the AV file area. To simplify the description, the control file (as a data file) is recorded as part of the latest file structure area. No magnetic cluster number is provided to the control file, and the control file is managed by the logical sector number. Alternatively, a data file may be recorded in the magnetic cluster in the AV file area as a data file for controlling the AV file information. In Example 3, the AV directory area, the root directory area, the data files, and the FAT area are recorded in the latest file structure area according to the basic file structure recording device 26. The structure of the FAT has the function of a space management structure, and the FAT performs file management. Therefore, the FAT is processed by the basic file structure recording device and the basic file structure playback device. In Example 3, the starting point information for performing sequential recording is recorded in bit 1. It will be apparent that the starting point information can be indicated by other values (such as FFh). In Example 3, a data structure (such as a FAT) can also be used to obtain the starting position of the sequential record, in which the information of the unconfigured areas and the link information of the files are managed by the same table. In this case, it is also possible to record the AV file sequentially, while avoiding overwriting of data in the AV file area. In Example 2, the starting unit number is registered at the front end of the space management structure. In Example 3, the starting point information is registered as a part of each magnetic cluster information in the space management structure. If the starting point information is registered in the reserved byte of each magnetic cluster information, then the file system can be compatible with the computer operating system before (63), and There is no need to expand these FAT standards. The two-stage defect management device described in this example 2 is applicable to the latest file structure area including the FAT area in this example. A magnetic cluster which has become defective in this AV file area and becomes unusable can be registered in FAT 1710 of FAT area 1704. In this case, FFh is registered as, for example, the value of the starting point information. 4. Example 4 In Example 4, a representative defect management method is described when an AV file, a control file, and a volume file structure are sequentially recorded on a disk that limits the number of times data can be rewritten. Even if "sequential recording is used to prevent the data from being overwritten in a special area in order to prevent a defective area from occurring" as in Example 1, the total number of defective areas still increases as the number of times the disk is used. In the following description, A defective area contains an area where data cannot be recorded or played, and a minimum unit of the defective area is an ECC block. 4.1 Data Structure of the Disc Figure 17 illustrates a representative data structure of the disc 2 3 5 The volume space includes defect areas 1902, 1906, 1906, and 1910. A defect list structure area 1908 is configured, and the defect areas are registered in the defect list structure area 1908. A system information is recorded in the defect list structure area 1908 Stream directory 1923 (in which a data structure of the system is registered), a file registration 1924 in the system data stream directory 1923, and a file registration 1925 in a non-configurable spatial data stream. The non-configurable -64- 1235361 Ming Gu. ( 60)-A spatial data stream is a resource defined to register a defective area or area. Material structure, in which a magnetic volume file structure cannot be allocated in the defective area or the child area. In this example, 'utilize the non-configurable space data. The stream registers the location information of the defective area. &Quot;' FIG. 18 illustrates a file for recording a file on the optical disc 235. Record processing procedure = The file recording process is performed by the information recording and playback device shown in FIG. 2. The details will be described later. The steps shown in Fig. 18. In the following example, the AV file (AV file-0 is recorded on a disc 2 3 5 having the data structure shown in Fig. 17). (S2001 ) The system control area 201 starts the AV file (AV file_0 sequentially recorded in the unallocated area) from the unallocated area of the designated registration sector number. A defect was detected while recording the AV case. If the area is NO6, the system control area 20 1 skips the defective area and continues to record into the next unconfigured area. If it is' the areas where the AV building case is actually recorded is one of the AV building case area 1905 The first amplified 192 1 and an AV archive area 1907 Second augmentation 1922. For example, by executing a control program built in the system control area 201 as a file recording device 2 1 3, the above-mentioned operation of the system control area 2 01 is achieved (S2002) system control Area 201 generates a location where the first expansion 1921 (where the AV file (AV file-c) is recorded) and the second expansion 1922 (where the location of the AV building (AV file-c) is recorded % File registration of information (AV file-c). Then, the system control area 201 stores the file registration (AV building case-c) 14? In the basic file structure memory 2 3 5 of the memory circuit 263. -65- 1235361 (61) Sighed that Meng continued to buy (S2003) system control area 2 0 1 records a control file (data file) 1 4 8 on a rear unconfigured area. When a defective area is detected while recording the control file, the system control area 2 0 1 skips the defective area and continues recording to the next unconfigured area, as described in step (S2001) The same is true for the case where the AV file is recorded. (S2004) The system control area 201 generates a file registration (data file) 149 in which position information of the area (amplification) is registered, and a control file (data file) 1 48 is recorded in the area. Next, the system control area 20 1 stores the file registration (data file) 1 4 9 in the basic file structure memory 2 3 5 of the memory circuit 2 6 3. If the control file is recorded in a plurality of amplifications because a defective area is detected, when recording position information of the control file is registered, all such amplification position information will be registered, just like the AV The case of the file is the same. (S2005) The system control area 201 generates a defective list structure of the system data stream directory 1924 and the system data stream directory 1924 for file registration 1923. The system control area 20 1 also generates a file registration of a spatial data stream 1 9 2 5, in which the location information of a defective area detected in the magnetic volume space is registered in the configured spatial data stream. The system control area 2 0 1 stores the file registration 1 925 in the basic file structure memory 2 3 5. In addition, the system control area 2 0 1 generates an unconfigured space registration 1 9 2 5, in which the location information of the unconfigured space is registered in the space registration 1 925, but does not include the “unconfigured” recorded in the archive record processing Area "and" Position information of the defective area detected in the archival processing of this file -66- Fathom _Continue to buy 1235361 (62) ". Then, the system control area 2 0 1 will register the unallocated space 1 9 2 5 is stored in the basic file structure memory 23 5. The system control area 20 1 also generates an AV directory (AVDir) 150 (including the recorded AV file and the control file information), and a file collection description item 1 5 2 , Root directory 1 5 3, the file registration of the root directory 1 5 4, which records the recorded AV files "(AV file-a) 144" and "(AV file-d) 158", their location information and Attribute information is filed in 145 and 159, VAT 156, and VATICB 157. The system control area 201 stores this data in the basic file structure memory 2:35. (S2 006) The system control area 201 will record the basic file structure, the defect list structure, the space management structure 1 23 and the V AT structure generated in steps (S2002), (S2004) and CS2005) in the latest File structure area 13 1. (52007) If a defective area is detected while data is being recorded in the latest file structure area 1 31, perform the following steps (S2008) ... etc. When the record is completed and no defects are detected, the record processing of the file is terminated. (52008) System control area 2 0 1 Updates the defects in the space management structure. List structure and registration information. The position information of a newly detected defect area is registered in the non-configurable spatial data stream of the defect list structure. The position information of a newly detected defective area is eliminated from the non-configurable spatial data stream of the space management structure. (52009) The system control area 201 designates the subsequent unconfigured area in order to record the data in the latest file structure of the update. -67- 1235361 (63) Trigger _ Continued page For example, by executing a control program built in the system control area 2 0 1 in this file structure and recording the green control device 261 to achieve the system control area described in step (S2009) 20 1 assignments. In the record processing of the AV file in this example, an area where an execution record was checked and an error was reported that resulted in the inability to complete the record was identified as a defective area. Generally speaking, the information to be recorded in the magnetic volume and the latest file structure area is recorded by checking; and the data to be recorded in the AV file area is not checked. Alternatively, the data to be recorded in the AV file area may be recorded in a format. The data to be recorded in the magnetic volume structure area and the latest file domain can be recorded in a manner. The data recorded in the AV file area can be identified by “placing the area without any defects” in order to save the time of replacement. If so, identifying a defect when playing the file can separate π—a defect management device used to record a domain ”and“ one application of another defect management device used to record a domain ”from each other so that the file is based on the file The characteristics can change the defect. It is also possible to register an area where the file cannot be played back as a domain. Use a defective area which is registered as a non-configurable empty location information to reformat the media. If so, keep the spatial data stream Until the media is reformatted, the location information of the detected defective area can be recorded in green as the base (S200 1) ~ The case structure is to record the required area to be processed. The area management of the area of the data The area management of the data should be filled with a defective interval The data stream should not be matched. The magnetic volume is empty -68- For example, the location information can be managed in the registration block of the record information section in Example 1. The device described in this example can be applied Example 3. When defect management is performed, data is recorded while jumping over a defective area, and defect information is registered in the FAT. As described above, in this example, when repeated in a repeatable When sequential recording is performed on a read-write medium, it can be recorded in the subsequent area while avoiding a detected defect area not being replaced. If so, when a repeatable read-write recording medium has a total number of detected defects, When the use conditions change significantly, and when the capacity is insufficient, 'you do not need to obtain a spare area or expand the spare area in advance. The area in the media can be effectively used. Example 5 In Example 5, A representative data structure for a disk that limits the number of times of data rewriting due to an increase in density, a registered sector number for performing sequential loop recording from an inside to an outside of the disk, and a representative In this example, a registered volume number is recorded in the volume volume managed by the file system, instead of being recorded in the record information area In the example 1, the record information section includes a counting unit and a plurality of registration units in order to improve the reliability of the registered sector number of the disk that limits the number of times of data rewriting. In this example, the The data structure defined by the ECMA 167 can be updated to improve the reliability of the registered sector number; and because the registered sector number is recorded, the record information section is not needed. If so, in this example -69- 1235361 _ (65) I read and read: The technique described on the car's continuation page is applicable to general-purpose disks. Figure 19 is a data structure of an updated registration volume number recorded in the volume structure.

The function of a registration sector number 3 03 2 is the same as that described in these other examples. In FIG. 19, the registration sector number 3 0 3 2 indicates the address of the VAT ICB 157 in the VAT structure area. Domain 104 in the latest file structure area 13 1. Record the registration volume number 3 0 3 2 in a logical disk group integrity description item sequence 3 0 1 1 one logical disk group integrity description item 3 0 3 1 in the field of the processing system . The logical disk group integrity description item records integrity information and indicates whether the file structure recorded in the magnetic volume space is correct. Therefore, the reliability of the registered sector number can be further improved by recording the registered sector number in the logical disk group integrity description item.

The location information of the logical disk group integrity description item sequence 3 0 1 1 is recorded in a logical volume description item sequence 3 0 1 0 in a logical disk group description item 3 0 2 2. Provide a magnetic volume description item sequence 3 0 1 to record a description item about a magnetic volume. A main magnetic volume description item 3 0 2 1 and a partition description item 3 0 2 3 are recorded in the magnetic volume description item. The position information of the magnetic volume description item sequence 3 0 1 0 is recorded in an anchor magnetic volume description item index 3 04 1. The anchor volume description item index is recorded in a fixed sector on a logical sector number 2 5 6. Although not shown, the anchor volume description item index is also recorded in the logical volume number N-2 5 6, where N is the logical volume number of the outermost part of the volume volume. Since the anchor magnetic volume description item index is recorded twice, even if one of the indicators cannot be read -70- 1235361 (66), it is still beneficial. Use the other anchor magnetic volume description item index. Figure 20 illustrates a procedure for updating and recording a green zone number. An update device for registering a sector number will be explained. (S3 001) In terms of the logical disk group integrity descriptor sequence, an area corresponding to, for example, 32 sectors is reserved. The logical disk group integrity description items are sequentially recorded starting from the front end of the logical disk group integrity description item sequence, and the last recorded volume integrity description item is identified as a valid description item. The registration volume number is updated by recording a logical disk group integrity description item in the subsequent logical volume. When there is no logical volume behind, 0 0 h is recorded in the logical disk group integrity description item sequence in all of its logical partitions, and the logical disk group integrity description item is recorded in the logic Disk group integrity describes the front end of a sequence of items. (S3 002) When recording a logical disk group integrity description item, it will be checked whether the logical volume to be recorded is a defective volume. When it is not a defective magnetic field, the process is terminated. When it is a defective magnetic area, the process proceeds to step (S3003), in which a logical disk group integrity description item sequence is re-reserved in a blank area of the magnetic volume structure area in order to record the logic Disk group integrity description. In this way, when the number of data rewrites of a disk is limited to 100 times, a logical disk group integrity description item can be recorded in green 32 using the same logical disk group integrity description item sequence. X 100 times. When a logical disk group integrity description item sequence is reconfigured, -71-1235361 (67) Release Notes The continuation page must record a logical disk group used to manage the logical disk group integrity description location information Description item. (S3004) As far as the magnetic volume description item sequence is concerned, an area like 16 magnetic areas is reserved. The logical disk group description item contains a field of a volume description item number. When a plurality of logical disk groups are recorded in the volume description item sequence, the logical disk group description item having the maximum volume volume number is valid. As far as recording the logical entry is concerned, the magnetic sector is searched from the front of the magnetic volume description entry sequence. These logic descriptors are recorded starting from the leading blank logic pole magnetic field. When there is no blank logical volume, the old logical disk group description items are recorded at oh to generate a blank logical record. Then, the logical blank description items are recorded from the leading blank logical volume. (S3 005) When recording a logical disk group description item, it will check whether the logical volume recorded is a defective volume. When it is not a zone, the process is terminated. When it is a defective sector, proceed to step (S3006), in which a logical disk sequence is re-reserved in a blank area of the volume structure area, the logical disk group integrity description item, together with a master The magnetic volume describes a partition description item. In this way, when the number of data rewrites of a disk is limited to an odd number, the same logical disk group description item sequence can be used to record the disk group description item (16-2) X 100 times. (S3007) When a magnetic volume description item sequence is reconfigured, the item sequence corresponds to an example of a 4 item description, a description item description, an item sequence, a disk group, a blank logical compilation, a disk assembly, and all of these sectors. The disk group should record a defective magnet, then the processing group description item should be recorded in order to record the item and a J is 100 times. A logic must be updated -72-1235361 (68) and recorded to manage the magnetic volume. An index of the magnetic descriptive item of the position information of the sexual description item sequence. Since the registered sector number is gradually updated and recorded in this way, even on a disk whose data rewriting limit is limited to 100 times, a total of (32 X 100) X ((16-2 ) X 100) X 100 times. The steps for updating and recording can be changed with the required number of data rewrites. It will be apparent that when 1 000 rewrites are sufficient, the registered sector number may be rewritten in the same logical disk group integrity description entry sequence. Industrial Applicability An information recording medium according to the present invention defines a use order of unconfigured areas registered in a space management structure, and moves a latest file structure area from an inside to an outside while recording data. If so, the data is prevented from being damaged or flawed due to centralized rewriting, and the reliability of the data can be improved.
