Description

Optical recording information storage medium, recording / reproducing apparatus, recording / reproducing method, and computer readable recording medium having recorded thereon a program for performing the method. (Optical recording medium, recording / reproducing apparatus, recording / reproducing method and recording medium storing a program to implement the method}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the field of optical discs, and more particularly, to an optical record information storage medium, a write-once information storage medium, and a rewritable information storage medium for managing access control related data for ensuring record / play compatibility. The present invention relates to a recording / reproducing apparatus, a recording / reproducing method, and a computer-readable recording medium having recorded thereon a program for performing the method.

Recently, due to the development of optical disk technology and semiconductor technology, new functions are frequently added after the standards for optical disk drive systems and optical systems including optical disks are finalized. Initially determined specifications should be updated.

1 is a reference diagram for explaining a problem according to the prior art.

When the old standard is called "old standard" and a new function is added to the old standard and the updated standard is called "new standard", the old standard disk 12 is made to operate in the old standard drive system 11, The new standard disk 14 is made to be operated in the new standard drive system 13.

The old and new specifications may or may not be compatible with recording / playback due to new features added. The two standards are compatible with recording / playback, indicating that the old standard disc 12 used in the old standard drive system 11 can be recorded / played in the new standard drive system 13, and also new The new standard disc 14 used in the standard drive system 13 indicates that recording / playback is also possible in the old standard drive system 11.

In order to ensure mutual recording / playback compatibility between the old standard and the new standard and the two standards by the addition of the new function as described above, when the disc 14 of the new standard having the new function is loaded in the old standard drive system 11 There is a need for the old standard drive system 11 to respond appropriately to the new function. To this end, when the old standard is enacted, it is necessary to prepare a proper response to the addition of new functions in the future. In addition, this appropriate countermeasure should be a general statement applicable to the new specification. The reason is that it should be applicable when new features are updated with newer features.

As a result, in order to have mutual recording / playback compatibility of a series of standards resulting from the addition of new functions, it is necessary to prepare for the addition of new functions when the standards are first created. To do this, it is necessary to establish the rules that the drive system should operate for functions known to the current specification and the rules that the current drive system should operate for the functions to be added in the future that the current specification does not know. In other words, when a new function is added to the current specification and a future specification is created, the drive system for the future specification stores an operation on the disk that the drive system for the current specification should perform for the new function. Thus, even when a disc of the future having a new function added to a drive system of the current standard is loaded, the information stored on the disc can be read to perform an operation for the new function. In other words, the drive system of the future specification can tell how to operate the disk to which the drive of the current specification is applied without knowing the new function itself added to the future specification.

In this context, when future discs with new features are added to a drive system of today's specification, there is a need for a drive system of the current specification to control access to future discs with new features. Furthermore, there is a need for a method capable of efficiently managing data for such access control.

The present invention will now be described in detail with reference to the accompanying drawings.

2 is a structural diagram of a write once information storage medium to which the present invention is applied.

2, in the disk 200 to which the present invention is applied, the lead-in area 210, the data area 220, and the lead-out area 230 are continuously provided.

The lead-in area 210 includes a pre-recorded area 211, a test area 212, an access control area 213, and a DMA # in which predetermined data is pre-recorded and used only for reproduction, at the time of disc manufacture. 2 (214), DMA # 1 (215), and TDMA (216). The test area 212, the access control area 213, the DMA # 2 214, the DMA # 1 215, and the TDMA 216 are recordable areas in which data can be recorded and changed.

In the prerecorded area 211, the information of the disc itself is prerecorded at the time of disc manufacture. For example, a disc ID, such as a disc manufacture number for identifying a disc, is recorded.

The test area 212 is an area in which the recording power and the like can be tested in order to record on the disc 200 in an optimal recording condition.

The access control area 213 is an area for recording information defining the operation of the drive system for new functions to be added in the future. In other words, it is an area in which common information is recorded so that even a drive system that does not know a predetermined function can perform access control to the disc 200. The access control region will be described in detail with reference to FIG. 3.

The DMA # 1 215 and the DMA # 2 214 are defect management areas, and are areas for recording information on defects generated in the user data area 122. When this recording medium is finalized and no further recording is performed, the last temporary defect management information recorded in the TDMA 216 is recorded in the DMA as final defect management information.

The TDMA 216 is an area in which defects generated while using this one-time recording medium 200 are managed, and temporary management information for data recording management is recorded and updated on this recording medium. TDMA 216 includes TDDS 410, TDFL 420, and RMD 430. In particular, an area is provided in the TDDS 410 of the TDMA 216 for recording status information for access control data blocks in the access control area 213 in accordance with the present invention. This will be described in detail with reference to FIG. 4.

The data area 220 includes a spare area # 0 221, a user data area 222, and a spare area # 1 223.

The user data area 222 is an area in which user data is recorded.

The spare area # 0 221 and the spare area # 1 223 are areas provided for the replacement block replacing the defective block generated in the user data area 222. This spare area is allocated to the data area when the disk is initialized or reinitialized.

The lead-out area 230 includes DMA # 3 231 and DMA # 4 232. The reason for having multiple DMAs as above is to improve the reliability of the disk by repeatedly recording the final defect management information of the finalized disk in several places.

FIG. 3A illustrates a first example of the structure of an access control area (ACA) shown in FIG. 2.

Referring to FIG. 3A, the access control area 213 includes access control data # 1 310, access control data # 2 320, and access control data # 3 330.

As described above, the access control area 213 is an area in which common information for access control to the disc is recorded, whether an existing standard or a new standard to which new functions are added. That is, it is an area for recording a common information table that is commonly applied to all functions used in the existing standard and the new standard to which new functions are added. Each Access Control Data (ACD) constitutes a common information table for each function. In other words, the access control data # 1 310 constitutes a common information table relating to "function 1", and the access control data # 2 320 constitutes a common information table relating to "function 2", and the access control data # 3 330 constructs a common information table regarding "Function 3". Here, for example, function 1 may be a function that the drive system can recognize, and function 2 and function 3 may be a function that the drive system cannot recognize. Of course, each access control data may include individual information that can be recognized only by the drive system that recognizes the function of the access control data, in addition to the common information that can be commonly recognized by all standard drive systems.

The access control data # 1 310 includes common information 311 and individual information 312.

The common information 311 includes ACD_ID 313, which is an identifier for identifying this access control data, formatability information 314 indicating whether or not format is possible, and spare area recording / representation indicating whether the spare area can be recorded or reproduced only. Playability information 315, and user data area recording / playback availability information 316 indicating whether recording of the user data area is possible or only playback is possible.

The drive system may determine whether this access control data relates to a recognizable function or to an unrecognizable function by checking the ACD_ID 313. That is, if ACD_ID 313 is an identifier that the drive system knows, this access control data relates to a function recognizable by the drive system, and if the drive system does not know this access control data relates to a function that the drive system does not recognize. will be.

In addition, even if the ACD_ID 313 is not recognized, the drive system may check a field included in the common information table, so that the drive system may perform a minimum appropriate operation even for an unrecognizable function.

Access control data # 2 320 also includes common information 321 and individual information 322, which has common information 321 having ACD_ID 323, which is an ID for identifying this access control data. The table includes format availability information 324, spare area recording / playback availability information 325, and user data area recording / playback availability information 326. FIG.

The access control area is preferably used continuously in the circumferential direction from the inner circumference of the disk and in the circumferential direction from the outer circumference of the disk. In addition, if an ACD block is found to be a defect in the access control area ACA through recording or after recording, it is recorded in the next block.

On the other hand, the recording / playback availability information regarding the areas shown in FIG. 3A, that is, the spare area and the user data area, may be further added to the common information of the access control data. It is preferable that no information is included. As will be described later, since the status information regarding such access control data will be recorded in the TDMA, if the recording of the TDMA is prohibited in the common information of the access control data, the status information of the access control data is also recorded or updated. Because it becomes impossible.

In other words, since the status information for each block of the access control area is recorded in the TDDS, it is preferable not to have information indicating whether or not recording / reproduction for TDMA is possible in the access control data. If the information indicating whether or not the TDMA can be recorded / reproduced in the access control data and the information is prohibited from being recorded on the TDMA, when the access control data block is recorded in the access control area for addition or modification, The change of state should be reflected in the TDDS, but there is a contradiction that the information cannot be reflected in the TDDS because the recording is prohibited on the TDMA. In addition, if the reproduction of the TDMA is prohibited, the status of each block of the access control region may not be known, which may cause difficulty in obtaining valid access control data.

In addition, the spare area itself may include all or part of the TDMA depending on the type of use of the recording medium once. In this case, it is preferable that the common information of the access control data does not include information on whether TDMA can be recorded or reproduced. In this case, the spare area recording / reproducibility information except for TDMA should be used.

FIG. 3B illustrates a second example of the structure of an access control area (ACA) shown in FIG. 2.

Referring to FIG. 3B, it is similar to the first example shown in FIG. 3A, except that the common information 311 includes TDMA recordability information 317 and data area record / reproducibility information 318. The common information 321 differs from the TDMA recordable information 327 and the data area recordable / reproducible information 328.

That is, in the second example, unlike in the first example, the recordability information of the TDMA is provided in the common information of the access control data. However, here, TDMA refers to a region of TDMA excluding TDDS. That is, as will be described later, since the state information on the access control data is stored in the TDDS, even if the TDMA recordability information 317 is set to prohibited in the common information of the access control data, the TDDS should be in a recordable state.

On the other hand, although not shown in FIG. 2, such a TDMA may be allocated to a part of the data area as well as the lead-in area or the lead-out area. In such a case as well, the TDMA allocated to the data area may include a TDDS in which state information regarding access control data is stored. Therefore, even if recording or reproducing of the data area is prohibited, it should be possible to record or reproduce the TDD.

In other words, the TDMA recordability information 317 in the common information of the access control data is recording permission information excluding TDDS, and the data area recording / reproducibility information 318 is also recorded / reproduced in the data area excluding TDDS or TDMA. Indicates whether it is possible. That is, the TDDS should always be a recordable structure in the recording information storage medium once.

4 is a detailed structural diagram of TDMA provided with an area for recording ACD state information according to the present invention.

Referring to FIG. 4, the temporary defect management area (TDMA) 216 includes a temporary disc definition structure (TDDS) 410, a temporary defect list (TDFL) 420, and a recording management data (RMD) 430. .

The TDFL 420 is an area for temporary defect management, and is an area for recording, for example, the address of a defect block and the address information of a replacement block replacing the defect block as information about a defect generated in the user data area. to be.

The RMD 430 is an area for recording management. The RMD 430 is divided into two types according to the data recording method. When the medium is used in the sequential recording mode, the RMD 430 is managed by the sequential recording information. When the medium is used in the random recording mode, it is managed by a space bit map (SBM).

The TDDS 410 is an area for temporary disc management, an area for recording information for disc management, and in particular, state information 411 of access control data is recorded according to the present invention.

The state information 411 of the access control data is a portion for recording each state of the access control data blocks in the access control area. Referring to FIG. 4, two bits are allocated for each state information of each access control data block, and 64 * 2 = 128 bits are allocated by allocating 2 bits for each block for 64 blocks in the access control region. Therefore, 16 bytes (B0, B1, ... B15) are allocated for the status information of all the access control data blocks in the access control area.

5 is a reference diagram for explaining a state included in ACD (Access Control Data) state information according to the present invention.

Referring to FIG. 5, the state of each access control data block is represented by 2 bits and includes four states, that is, "00", "01", "10", and "11".

"00" indicates that the access control data block can be used to write the access control data.

&Quot; 01 " indicates a defective block, specifically, 1) a block found as a defect while writing the access control data block in the access control area, 2) a defect block in which invalid access control data is recorded, and 3) the same 4) One-time-recording disc in which access control data information having ACD_ID is requested so that the updated access control data is written to another access control data block, and the updated access control data which is not updated is recorded. By the finalizing, any one of the states indicating that the unrecorded area of the access control area is filled with specific data is indicated.

&Quot; 10 " indicates that a block was found which was found to be defective while reproducing the access control data recorded in the access control area, but a valid ACD was recorded.

"11" indicates that a valid ACD is a written block.

When updating information for the same ACD_ID is requested during disk use, for existing recorded ACD blocks, switch the bit information in the TDDS to "01" to indicate the block in which the invalid ACD has been written, and also update the updated ACD block. Write to the next available block of the access control area.

A specific example of recording the state information of the access control data block will now be described with reference to Figs. 6A to 8B.

FIG. 6A shows a first example of the recorded access control data block state of the access control area shown in FIG.

Referring to Fig. 6A, two valid access control data blocks # 1 and # 2 are recorded in an access control area 213 of 64 blocks, and the remaining 62 blocks are not yet recorded for data and will be used for later recording. It can be a block.

6B is an example of access control data block state information in the TDDS according to the block state shown in FIG. 6A in accordance with the present invention.

Referring to FIG. 6B, an area 411 provided to record ACD status information of the TDDS 410 is 16 bytes to contain status information of 64 blocks in the access control area illustrated in FIG. 6A. .

Since both block # 1 and block # 2 of the access control area are blocks in which valid access control data is recorded, " 11 " is recorded in b127 and b126 to indicate status information for each block, and in " 125 " 11 "is recorded. The status information for each block from b123 to b0 is represented as "00" to indicate that the remaining 62 blocks have not been used yet, so that they can be used for recording of the ACD block later.

7A and 7B are diagrams for explaining the change of access control data state information in the TDDS due to the update and the defective block of the ACD.

FIG. 7A is a second example of the recorded access control data block state of the access control area shown in FIG.

Referring to FIG. 7A, in the access control region state of FIG. 6A, an update of the ACD block # 1 recorded in the first block of the access control region is requested, and thus the ACD block # 1 in the third block, which is the next available region in the access control region, is requested. It indicates that the updated ACD block # 1 is recorded in the fourth block, which is found to be a defect through the test during or after recording. Thus, the first block is an invalid access control data block, the third block is a defective block, the fourth block is a block in which valid access control data is written, and the remaining 60 blocks are free blocks that have not yet been written. to be.

7B is an example of access control data block state information in the TDDS according to the block state shown in FIG. 7A in accordance with the present invention.

Referring to FIG. 7B, since the first block of the ACA is no longer valid due to the update of the ACD block # 1, update the value of the bit 126 to "01" in bit 127 of the ACD status information field of the TDDS. The state information for the first block is maintained as it is unchanged, and since the third block is found to be defective during the recording or after the test, the value of bit 122 is updated to "01" to reflect this. In addition, the fourth block indicates that since the updated valid ACD block # 1 has been recorded, the value of the bit 120 has been updated to "11" in bit 121 to reflect this.

8A and 8B are diagrams for explaining changes in ACD state information in the TDDS due to a reproduction error of the ACD block.

8A is a third example of the recorded access control data block state of the access control area shown in FIG.

Referring to FIG. 8A, a write once storage medium having a state of the access control area of FIG. 7A is loaded into the drive system so that the valid ACD block # 1 and the valid ACD block # 2 are valid from the access control data state information in the TDDS of FIG. 7A. Indicates that the error correction cannot be made during reproduction of the ACD block # 2 recorded in the second block of the access control region in the process of reproducing. That is, since only the state where an error occurred during reproduction of the second block is shown, the state of the access control area shown in FIG. 8A is substantially the same as that of the access control area shown in FIG. 7A.

8B is an example of access control data block state information in the TDDS according to the block state shown in FIG. 8A in accordance with the present invention.

Referring to FIG. 8B, access control data in the TDDS corresponding to the second block of the access control area to indicate that ACD block # 2, which is the second block of the access control area, has not been reproduced but still has a valid ACD block recorded. It can be seen that the value of bit 124 is updated to "10" in bit 125 of the status information field.

 The reason for this update to "10" is that even if the second access control data block cannot be reproduced in the currently loaded drive system, it may sometimes be reproduced by other high performance drive systems. If the block can be played on another drive system, the information can be replaced with a good block, so ACD block # 2, the second block in which a playback error occurred when this disc was loaded in another drive system in the future. It is possible to provide the convenience of using the disc by playing back the ACD block transferred to the good block without playing back again.

Furthermore, when finalizing the final state preservation of the recording information storage medium once, the final TDDS is recorded in the DMA as DDS information, thereby accessing the data in the DDS to change the recording state for the illegal change or addition of information in the future access control area. The control data state information can be compared with the recording state of the actual access control area on the disc. This is because the ACD status information field in the TDDS reflecting the final state of the access control area is copied and recorded in the DDS recorded in the DMA after the finalization.

9 is a structural diagram of a rewritable information storage medium to which the present invention is applied.

Referring to FIG. 9, in the disc 900 to which the present invention is applied, the lead-in area 910, the data area 920, and the lead-out area 930 are continuously provided.

The lead-in area 910 includes a pre-recorded area 911, a test area 912, an access control area 913, and a DMA # in which predetermined data is pre-recorded and used only for reproduction at the time of disc manufacture. 2 914 and DMA # 1 915.

The data area 920 includes a user data area 922 in which user data is recorded, a spare area # 0 921 allocated for recording replacement blocks for replacing defects generated in the user data area, and a spare area # 1. (923).

The lead-out area 930 includes DMA # 3 931 and DMA # 4 932.

The structure of the rewritable information storage medium shown in FIG. 9 is almost the same as that of the write once information storage medium shown in FIG. 2 except that the rewritable information storage medium can be re-recorded, thereby managing temporary defects. Since there is no need for TDMA separately, it can be seen that it has only DMA as a defect management area.

In the rewritable information storage medium 900, the DMA is an area for recording a Disc Definition Structure (DDS) for defect management and disc management and a Defect List (DFL) for defect information. For example, DMA # 1 915 includes DDS 1110 and DFL 1120.

FIG. 10A is a first example of the structure of the access control area shown in FIG.

Referring to FIG. 10A, the access control area 913 includes access control data # 1 1010, access control data # 2 1020, and access control data # 3 1030.

The access control data # 1 1010 includes common information 1011 and individual information 1012.

The common information 1011 includes ACD_ID 1013, which is an identifier for identifying this access control data, formatability information 1014 indicating whether or not format is possible, and spare area recording / representation indicating whether the spare area can be recorded or reproduced only. Playability information 1015, and user data area recording / playback availability information 1016 indicating whether recording of the user data area is possible or only playback is possible.

Access control data # 2 1020 also includes common information 1021 and individual information 1022, which has common information 1021 having ACD_ID 1023, which is an ID for identifying this access control data. The table includes format availability information (1024), spare area recording / reproduction availability information (1025), and user data area recording / reproduction availability information (1026).

FIG. 10B is a second example of the structure of the access control region shown in FIG.

Referring to FIG. 10B, it is similar to the first example shown in FIG. 10A, except that the common information 1011 includes DMA recordable information 1017 and data area recordable / reproduced information 1018. The common information 1021 is different from the DMA recordable information 1027 and the data area recordable / reproducible information 1028.

That is, in the second example, unlike in the first example, the DMA recordable information is provided in the common information of the access control data. However, DMA here refers to an area of the DMA excluding DDS. That is, as will be described later, since the state information relating to the access control data is stored in the DDS, even if the DMA recordable information 10 is set to prohibited in the common information of the access control data, the DDS should be in a recordable state. That is, in a rewritable information storage medium, the DDS should always be recordable.

It can be seen that this access control area is the same in either the recording medium or the rewritable medium.

If an ACD block is found to be faulty during the write or in the post-write test in the access control area, it is written to the next available block.

Upon reinitialization of the disk, the drive system clears the ACD by rewriting the previously recorded ACD blocks to a specific value such as 00h or FFh. In addition, upon initializing or reinitializing the disk, the drive system writes the ACD for the functions it knows into the access control area, and the remaining unrecorded area of the access control area fills with a specific value such as 00h or FFh.

11 is a detailed structural diagram of a DMA provided with an area for recording ACD state information according to the present invention. As it is a rewritable medium, ACD status information is immediately recorded in the DMA.

Referring to FIG. 11, a defect management area (DMA # 1) 915 includes a Disc Definition Structure (DDS) 1110 and a DeFect List (DFL) 1120.

The DFL 1120 is an area for defect management, and is an area for recording the address of a defect block and the address information of a replacement block that replaces the defect block as information about a defect generated in the user data area. .

The DDS 1110 is an area for disc management, an area for recording information for disc management, and in particular, state information 1111 of access control data is recorded according to the present invention.

The state information 1111 of the access control data is a portion for recording each state of the access control data blocks in the access control area. Referring to FIG. 11, two bits are allocated for each state information of each access control data block, and 64 * 2 = 128 bits are allocated by allocating 2 bits for each block for 64 blocks in the access control region. Therefore, 16 bytes (B0, B1, ... B15) are allocated for the status information of all the access control data blocks in the access control area.

Each state of the access control data block of the rewritable recording medium can be represented in four states as in the state information of the access control data block of the recording medium once, as shown in FIG. However, the details of the specific state are somewhat different.

In the rewritable medium as shown in FIG. 5, the state of each access control data block is represented by 2 bits, and includes four states, namely, "00", "01", "10", and "11".

"00" indicates that the access control data block can be used to write the access control data.

&Quot; 01 " indicates a defective block, specifically, 1) a block found as a defect while writing an access control data block in the access control area, or 2) a state indicating that the invalid access control data is a recorded defective block. It represents either.

&Quot; 10 " indicates that a block was found which was found to be defective while reproducing the access control data recorded in the access control area, but a valid ACD was recorded.

"11" indicates that a valid ACD is a written block.

In addition, if the ACD recorded in the access control area is no longer valid while the disk is in use, the ACD block is filled with a specific value such as 00h or FFh, indicating that the state for the block is available. To 00 ". This is to prevent incorrect access control data from being read in the case where the status information or the like cannot be read, even if the status information for the invalid access control data block is marked as "00" and available. to be. That is, in order to more reliably prevent the invalid access control data from being reproduced, it is preferable to fill the invalid access control data block with a specific value, for example, 00h or FFh.

When updating information for the same ACD_ID is requested during disk use, for existing recorded ACD blocks, switch the bit information in the TDDS to "01" to indicate the block in which the invalid ACD has been written, and also update the updated ACD block. Write to the next available block of the access control area.

A specific example of recording the state information of the access control data block will now be described with reference to Figs. 12A to 14B.

FIG. 12A is a first example of the recorded access control data block state of the access control area shown in FIG.

Referring to Fig. 12A, two valid access control data blocks # 1 and # 2 are recorded in an access control area 913 of 64 blocks, and the remaining 62 blocks are not yet recorded so that they can be used for recording later. It can be a block.

12B is an example of access control data block state information in the TDDS according to the block state shown in FIG. 12A in accordance with the present invention.

Referring to FIG. 12B, an area 1111 provided to record ACD status information of the DDS 1110 is 16 bytes to hold status information of 64 blocks in the access control area illustrated in FIG. 12A. .

Since both block # 1 and block # 2 of the access control area are blocks in which valid access control data is recorded, " 11 " is recorded in b127 and b126 to indicate status information for each block, and in " 125 " 11 "is recorded. The status information for each block from b123 to b0 is represented as "00" to indicate that the remaining 62 blocks have not been used yet, so that they can be used for recording of the ACD block later.

13A and 13B are diagrams for explaining the change of access control data state information in the DDS due to the update and the defective block of the ACD.

FIG. 13A is a second example of the recorded access control data block state of the access control area shown in FIG.

FIG. 13A shows that ACD block # 1 recorded in the first block of the access control area in the state of the access control area of FIG. 12A is no longer needed and is overwritten with 00h, and also the ACD block # 3 for the new function in the third block. The ACD block # 3 is recorded in the fourth area, the next block, which is found to be a defect during recording or after recording.

That is, the first block of the access control area 913 is filled with 00h, the second block has a valid ACD block # 2 recorded, the third block is a defective block, and the fourth block has a valid ACD block # 3. The remaining 60 blocks are blocks that have not been written yet and are usable.

13B is an example of access control data block state information in the TDDS according to the block state shown in FIG. 13A in accordance with the present invention.

Referring to FIG. 13B, as the first block of the access control area is overwritten with 00h, the status information for the first block of the DDS 1110 is set from bit 127 to bit "126" for later use. Update. The state information for the second block remains unchanged because it remains unchanged, and the third block has a value of "01" in bits 123 to reflect this because the third block was found to be defective during the write or post-write test. Update it with In the fourth block, since the valid ACD block # 3 for the new function is recorded, the value of the bit 120 is updated to "11" in bit 121 to reflect this.

14A and 14B are diagrams for explaining changes in ACD state information in the DDS due to a reproduction error of the ACD block.

FIG. 14A is a third example of the recorded access control data block state of the access control area shown in FIG.

FIG. 14A illustrates a process in which a rewritable information storage medium having a state of an access control area shown in FIG. 13A is loaded into a drive system to reproduce valid ACD block # 2 and valid ACD block # 3 from an ACD status information field in the DDS of FIG. 13A. Indicates that the ACD block # 2 recorded in the second block of the access control region cannot be error corrected during reproduction. That is, since only the state where an error occurred during reproduction of the second block is shown, the state of the access control area shown in FIG. 8A is substantially the same as that of the access control area shown in FIG. 7A.

14B is an example of access control data block state information in the TDDS according to the block state shown in FIG. 14A in accordance with the present invention.

Referring to FIG. 14B, access control data in the DDS corresponding to the second block of the access control area to indicate that the second block of the access control area, ACD block # 2, has not been reproduced but is still valid. It can be seen that the value of bit 124 is updated to "10" in bit 125 of the status information field.

 The reason for this update to "10" is that even if the second access control data block cannot be reproduced in the currently loaded drive system, it may sometimes be reproduced by other high performance drive systems. If the block can be played on another drive system, the information can be replaced with a good block, so ACD block # 2, the second block in which a playback error occurred when this disc was loaded in another drive system in the future. It is possible to provide the convenience of using the disc by playing back the ACD block transferred to the good block without playing back again.

15 is a schematic block diagram of a recording / reproducing apparatus according to the present invention.

Referring to FIG. 15, the recording / reproducing apparatus includes a recording / reading unit 2 and a control unit 1.

The recording / reading section 2 is provided with a pickup or the like to record data on the disk 100 and read out the data recorded on the disk 100. In this case, the disc 100 includes a disc 200 which is a write-once optical information storage medium to which the present invention is applied or a disc 900 which is a rewritable information storage medium.

The control unit 1 controls the recording / reading unit 2 to record and read data on the disc 100 according to a predetermined file system. In particular, the control unit 1 according to the present invention provides access control data status information to a defect management area provided in the lead-in area of the disc for managing the state of the access control data block recorded in the access control area provided in the lead-in area of the disc. An area is allocated, and the state information of each access control data block is recorded and managed in the access control data state information area.

The control unit 1 includes a system controller 10, a host I / F 20, a DSP 30, an RF AMP 40, and a servo 50.

In writing, the host I / F 20 receives a predetermined write command from the host 3 and sends it to the system controller 10. The system controller 10 controls the DSP 30 and the servo 50 to carry out the write command received from the host I / F 20. The DSP 30 adds additional data such as parity for error correction to the data to be recorded received from the host I / F 20 and performs ECC encoding to generate an ECC block, which is an error correction block, and then, in a predetermined manner. Modulate. The RF AMP 40 converts the data output from the DSP 30 into an RF signal. The recording / reading section 2 provided with the pickup records the RF signal transmitted from the RF AMP 40 on the disk 100. The servo 50 receives a command necessary for servo control from the system controller 10 to servo control the pickup of the recording / reading unit 2.

At the time of reproduction, the host I / F 20 receives a reproduction command from the host 3. The system controller 10 performs initialization necessary for regeneration. The recording / reading unit 2 outputs an optical signal obtained by irradiating a laser beam to the disk 100 and receiving a laser beam reflected from the disk 100. The RF AMP 40 converts an optical signal output from the recording / reading section 2 into an RF signal and provides modulated data obtained from the RF signal to the DSP 30, while providing a servo signal for control obtained from the RF signal. Provided to the servo 50. The DSP 30 demodulates the modulated data and outputs data obtained through ECC error correction. On the other hand, the servo 50 receives the servo signal received from the RF AMP 40 and the command required for the servo control received from the system controller 10 to perform servo control for the pickup. The host I / F 20 sends data received from the DSP 30 to the host. The system controller 10 controls the servo to read disc management information or defect information from the disc for reproduction control and to read data from the position where the defect free data is recorded.

The recording / reproducing apparatus shown in FIG. 15 may be implemented as a separate recording apparatus, a reproducing apparatus, or may be implemented by one recording and reproducing apparatus.

Now, the operation of recording and updating the state of the access control block in the recording / reproducing apparatus as shown in FIG. 15 will be described with reference to FIGS. 16 and 17.

16 is a flowchart illustrating a process of recording a state of an access control block according to the present invention.

First, upon initializing or reinitializing the disc, the system controller 10 writes an access control data block relating to a predetermined function in an access control area provided in the lead-in area of the disc 200 as a recording medium (step 1601). .

Next, the system controller 10 detects whether a defect is found in the access control data block by the write or post-write test (step 1602).

If a defect is found, the system controller 10 controls to rewrite the access control data to the next usable block of the access control area (step 1603).

The system controller 10 then controls to write to the TDDS with the state of the access control data block in which the defect is found as " 01 " (step 1604), and the state of the next block after the access control data is written again is " 11 ". Control to record in the TDDS (step 1605).

The system controller 10 then controls to write to the TDDS with the state of the blocks in which the access control data not recorded therein in the access control area as " 00 " (step 1607).

If no defect is found in step 1602, the system controller 10 controls to write to the TDDS with the state of the access control data block as " 11 " (step 1606), and proceeds to step 1607. do.

In FIG. 16, the disk initialization or reinitialization is described as an example. However, as shown in FIG. 16, the operation of recording the access control data and recording the status information according to the recording is limited at the time of initialization or reinitialization. Rather, the same may be applied in the situation of updating the access control data or recording new access control data even during the use of the disc. In addition, the same applies to the case of the rewritable medium, not the one-time recording medium, but the status information of the access control block will be recorded in the DDS, not in the TDDS.

17 is a flowchart illustrating a process of recording a state of a block in the case of updating an access control data block according to the present invention.

The recording medium is loaded into the recording / reproducing apparatus once, and the system controller 10 receives an update command of the access control data having the same identifier as the access control data recorded on this recording medium (step 1701).

First, the system controller 10 then controls to write to the TDDS by changing the state for that block to " 01 " since the block of already recorded access control data no longer has valid access control data (step 1702). .

The system controller 10 then controls to record the updated access control data in the next available block of the access control area of the recording medium once (step 1703).

The system controller 10 then controls to write to the TDDS with the status of the updated access control data block " 11 " (step 1704).

Recording / reproduction as described above can also be embodied as computer readable codes on a computer readable recording medium. The computer-readable recording medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and may also be implemented in the form of a carrier wave (for example, transmission over the Internet). Include. The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion. In addition, functional programs, codes, and code segments for implementing the recording / reproducing method can be easily inferred by programmers in the art to which the present invention belongs.
