Other objects and advantages of the present invention will be described in detail below, and learned from the embodiments of the present invention. [Embodiment] In order to make the above and other objects, features, and advantages of the present invention more comprehensible, a preferred embodiment is exemplified below in conjunction with the accompanying drawings for detailed description as follows. FIG. 2 is a diagram illustrating a structure of a single-write information recording medium, that is, a single-write disc 200 according to an embodiment of the present invention. Referring to FIG. 2, the single-write disc 200 includes a lead-in area 210, a data area 220, and a lead-out area 230 in this order. The lead-in area 210 includes a pre-recorded area 211, a test area 212, an access control area (ACA) 213, a defect management area (DMA) # 2 214, and DMA # 1 215

And temporary DMA (temporary DMA, TDMA) 216, in which pre-defined data is recorded in a pre-recorded area when a single-write disc 200 is produced. The pre-recorded area 211 is only available for reading. Test area 212, ACA 20053 ^ 1 ^ 213, DMA # 2 214, DMA # 1 215, and TDMA216 are areas where data can be written and rewritten. It must be understood that additional and / or less DMA, TDMA, test area, pre-recorded area, and / or ACA may be used, and the pre-recorded area may also be used for recording in other embodiments of the present invention. The pre-recorded area 211 stores information about the single-write disc 200, which is recorded therein when the single-write disc 200 is produced. For example, the pre-recorded area 211 stores a disc ID, which can confirm the disc production number of the single-write disc 200. However, it must be understood that other read-only information can be recorded in the pre-recorded area 211. The test area 212 is used to test a recording power and the like for optical recording on a single-write disc 200. ACA 213 is used to record the operation of the specified drive system for adding new functions later. The shared information that enables a drive system that cannot recognize certain functions to access the single-write disc 200 is recorded in the ACA 213. An example of the ACA 213 will be described in detail below with reference to FIG. 3. DMA # 1 215 and DMA # 2 214 are used to record information about defects occurring in a user data area (UDA) 222. When the single-write disc 200 is completed and data can no longer be written to the single-write disc 200, the final temporary defect management information recorded in the TDMA 216 will be recorded in the DMA as the final defect management information. -TDMA 216 records and updates information for managing defects occurring during the use of single-write discs 200 and temporary management information for managing the data recorded on single-write discs 200. TDMA 216 includes a temporary disc definition structure (TDDS) 410, a temporary defect list (TDFL) 420, and a recording management data (RMD) 430. The TDDS 410 includes an area in which status information about access control data (ACD) blocks included in the ACA 213 is recorded, which will be described in detail below with reference to FIG. 4. However, it must be understood that the status information can be recorded in other areas of the write-once disc 200. The data area 220 includes a spare area # 0 221, a UDA 222, and a spare area # 1 223. UDA 222 is used to record user data. The spare area # 〇 Φ 221 and the spare area # 1 223 provide spare blocks to replace defective blocks occurring in the UDA 222. This spare area is allocated to the data area 220 during the initialization or re-initialization of the single-write disc 200. The lead-out area 230 includes DMA # 3 231 and DMA # 4 232. Several DMAs are used to increase the reliability of the single-write disc 200 by repeatedly recording the same final defect management information in several parts of the single-write disc 200. However, it must be understood that additional or lesser amounts of DMA and other areas may be used and / or recorded in other areas of the write-only disc 200. FIG. 3A is a structural example diagram of the ACA shown in FIG. 2. Please refer to Fig. 3 'ACA 213 includes ACD # 1 310, ACD # 2 320 and ACD # 3 330. ', ACA 213 records public information used to access discs, whether existing or new standards. In other words, the ACA 213 stores a shared information table, k which can be used for all functions of existing and new standards. The ACD forms a common information sheet about the individual functions. For example, ACD # 1 310 is composed of, and the public month of power month b 1 is the flood meter, ACD # 2 320 is composed of the, 14 of the function 2, and the public 14 20 ° 53M〇c is composed of the information sheet, and ACD # 3 330 is composed of the The public information form of function 3, where "function 1," can be recognized by the drive system, and, function 2 "and, function 3, cannot be recognized by the drive system. ACD also includes specific information, which Only the drive system that can recognize the function corresponding to ACD can be identified, but not required in all aspects of the present invention. ACD # 1 310 includes public information 311 and specific information 312. Public information 311 includes ACD-ID 313 (that is, identifying ACD ID), formatting capability information 314 (indicating whether the disc can be formatted), spare area recording capability • capacity / reproducing capability information 315 (indicating whether the spare region can be recorded or only reproducing), and UDA recording capability / reproducing capability information 316 (indicates whether UDA is recordable or reproducible only). The drive system can judge whether ACD # 1 310 is about the identifiable function according to ACD-ID 313. In other words, if the drive system recognizes acd_id 313, then ACD # 1 310 Will be It is judged as an identifiable function, otherwise it will be judged as an unrecognizable function. In addition, even if the drive system does not recognize ACD_ID 313, the drive system φ can still use the fields included in the public information table to identify unrecognizable functions. Perform the least appropriate operations. ACD # 2 320 also includes public information 321 and specific information 322. Public information 321 includes ACD-ID 323 and contains formatting capability information 324, spare area recording capability / reproduction capability information 325, and UDA records. Capabilities The common information table of the reproduction / regeneration capability information 326. AC A 213 is used sequentially from the inner periphery of the single-write disc 200 to the outer periphery or from the outer periphery to the inner periphery, but it is not necessary. In addition, when data is written Until 200053mc, if the ACD block in ACA 213 is detected at the same time or after the verification result, a defect is detected, the data will be recorded in the subsequent ACD block. During this period, the public information of ACD includes Recording capacity / reproduction capacity information for spare areas of the single-write disc 200 and areas other than UDA 222. However, it is preferable that the common information does not include information about the recording capacity of the TDMA 216 / Capacity information, but not required. Status information about the ACD block is recorded in TDMA216, where ACD is recorded in the ACD block within the range of ACA 213. Therefore, if ACD's public information settings are set to prohibit writing to In TDMA, the status information about the ACD block cannot be recorded or updated. In other words, because the status information about the ACD block in the ACA 213 is recorded in the TDDS 410 included in the TDMA 216, the information about the TDMA 216 Recording capability / reproducing capability information should not be defined in ACD. If the information about the recording ability / reproducing ability of TDMA216 is defined in ACD and write prohibition is set to TDMA 216, when a new ACD block is added or an existing ACD block is changed in ACA213, the modified ACD status cannot be recorded in TDMA216. In this case, the actual state of each ACD block included in the ACA 213 cannot be known, which makes it difficult to obtain a valid ACD.

Meanwhile, the TDMA 216 may be wholly or partially included in the spare area 221 according to the usage of the single-write information recording medium. In this case, since the ACD • public information preferably does not include TDMA 216 recording capability / reproducing capability information ', the spare area recording capability / reproducing capability information should not include information about TDMA 216. 16

FIG. 3B is a diagram illustrating an exemplary structure of the ACA 213 shown in FIG. 2. The second example shown in FIG. 3B is similar to the example of FIG. 3A except that the common information 311 includes TDMA recording capability information 317 and data area recording capability / reproduction capability information 318 and the common information 321 includes TDMA recording capability information 327 and data. Area recording capability / reproduction capability information 328 〇 Please refer to FIG. 3A. In particular, the TDMA recording capability information 317 and 318 shown in FIG. 3B are included in the public information 311 and 312. However, even when the TDMA recording capability information 317 and 327 are set to prohibit writing to the TDMA 216, the TDMA recording capability information 317 and 327 still does not include information about the TDDS included in the TDMA 216 to cause the ACD status information to be recorded in the TDDS. In the meantime, although not shown in Fig. 2, TDMA 216 may be allocated in the data area, such as UDA 222. In this embodiment, the TDDS 410 for recording status information may also be included in the tdma 216 allocated in the data area. In this case, the TDDS included in the data area should be recordable / reproducible even when writing to or reading from the data area is prohibited. In other words, 'TDMA recording capability information 317 and 327 are for the recording capability of all parts of TDMA 216 except TDDS 410 §fl' and data area recording capability / reproduction capability information 318 and 328 are for information other than TDDS 410 or TDMA 216 Information on recording / reproducing capabilities in all data areas except Fig. 4 shows a detailed structure of the TDMA 216 according to an embodiment of the present invention. Fig. 4 is a diagram in which a temporary defect management area is provided together with an area in which ACD status information is recorded. Referring to FIG. 4, TDMA 216 includes TDDS 410, TDFL 420 and RMD 430. TDFL 420 is an area where information about defects occurring in UDA 222 (such as the address of a defective block and the address of a block replacing a defective block) is recorded for temporary defect management. rMD 43 0 is an area for record management. The RMD 430 is managed according to a recording mode. When the recording medium is recorded in a sequential recording mode, the RMD 430 is managed according to the sequential recording information. When 111 ^ 0 430 is recorded in a random recording mode, the RMD 430 is managed according to a Spacebitmap (SBM). TDDS 410 is an area where disc management information is recorded for temporary disc management. In particular, the ACD status information 411 according to the embodiment of the present invention is recorded in the TDDS 410. ACD status information 411 contains the status of each ACD block in ACA213. Referring to FIG. 4, 2 bits are allocated for status information about a single ACD block. Thus, the state information about 64 blocks in the definition ACA 213 is recorded, and 64 * 2 = 128 bits are allocated to the ACD state information 411. Accordingly, 16 bytes B0 ··· B15 are allocated for status information about each ACD block in the ACA 213. However, it must be understood that the number of blocks and / or the number of bits can vary. FIG. 5 is a schematic diagram illustrating an example of ACD block status information 411 included in the ACD status information according to an embodiment of the present invention. Referring to FIG. 5, the state of each ACD block is represented by 2 bits, that is, “00”, “01”, “10”, or “11” indicates one of the four states. 〇〇53 ^ d〇c In this example, bit "00" indicates that the ACD block can be used to record ACD, and bit "〇1" indicates that the ACD block is defective, and more specifically, bit "01" Represents the state where the ACD block is accumulated and tested as a defect when the ACD is recorded in the ACD block, the ACD block has an invalid ACD state, the ACD block has an old and invalid ACD and has the same ACD-ID as the old and invalid ACD The state of updating the ACD and recording the invalid ACD in other ACD blocks according to the request for updating the ACD and the state of the ACD block are one of the states of an unrecorded block filled with specific data according to the completion of a single write disc. Bit "10" indicates that the ACD block has a valid ACD when it was reproduced from the ACA, but was detected as a defect by 彳 彳. Bit '' 11 '' indicates that acd has a valid ACD. However, it must be understood that other bit combinations may be used. When an ACD update is requested during disc use, the bit recorded in TDDS to indicate the status of the ACD block with the old ACD will be changed to "01" to indicate that the ACD block has an invalid ACD and has The updated ACD of the old ACD with the same ACD-ID will be recorded in the ACD block available after the ACA213. An example of recording ACD block status information will be described in detail below with reference to FIGS. 6A and 6B. FIG. 6A is a schematic diagram illustrating an example of the state of the ACD block shown in the ACA213 of FIG. 2. Referring to FIG. 6A, the ACA 213 includes 64 blocks, including 2 ACD blocks # 1 and # 2 with valid ACDs, and 62 blocks on which no data is recorded and available for recording. FIG. 6B is a schematic diagram illustrating an example including ACD status information in the TDDS 410 according to the status of the ACD block in FIG. 6A. Referring to FIG. 6B, the TDDS 410 includes a 16-byte area to store aCD status information 411, which includes status information about 64 blocks included in the ACA 213 shown in FIG. 6A. To indicate ACD blocks # 1 and # 2 with valid ACD, bit "11" is recorded at positions bl27 and bl26 as status information, and bit "11" is recorded at positions M25 and bl24 as status information. In order to indicate that the other 62 blocks are not used but can be used for ACD recording, ,, 0, are recorded at each position bl23 to bO so that the status information about each 62 block can be expressed in bit "00". 7A and 7B show the ACD status information 411 recorded in the TDDS 410 according to the updated ACD and the occurrence of a defective block. FIG. 7A is an exemplary diagram showing the state of the ACD block shown in the ACA 213 of FIG. 2. FIG. In the case of requesting the update of ACD recorded in ACD block # 1 of FIG. 6A, if a defect is detected while the record update ACD is later available (ie, ACD block # 3), the update is responded to When a request is made or if a missing is detected during the verification period following the record update ACD, the update ACD will be recorded in ACD block # 4. As such, ACD block # 1 has invalid ACD, ACD block # 3 is defective and ACD block # 4 has valid ACD. The other 60 blocks in ACA 213 are unrecorded and available. FIG. 7B is a schematic diagram illustrating an example of ACD status information 411 included in the TDDS 410 according to the status of the ACD block in FIG. 7A. Please refer to FIG. 7B, since the ACD recorded in ACD block # 1 of ACA213 is no longer valid because of the ACD update, the bits of positions M27 and bl26 in TDDS 410 will be changed to "01". Since there is no change in ACD block # 2, the status information about ACD block # 2 is retained. Since ACD block # 3 2503_ ^ doc is detected as a defect during writing or as a result of verification after writing, the bits at positions bl23 and bl22 will be changed to "01". Due to the update, the valid ACD will be recorded in ACD block # 4, and the bits at positions bl21 and bl20 will be changed to "11". 8A and 8B show that the ACD status information 411 recorded in the TDDS 410 is changed according to an error that occurs when the ACD block is reproduced. FIG. 8A is an exemplary diagram showing the state of the ACD block shown in the ACA 213 of FIG. 2. FIG. The single-write information recording medium having the state of ACA213 shown in FIG. 7A can be arranged in the drive system, and the valid ACD basis when recorded in ACD blocks # 2 and 4 of ACA213 respectively is included in the TDDS 410 shown in FIG. 7B. Errors that occur when ACD status information is reproduced can be corrected during reproduction. Since FIG. 8A shows the state of the block until an error occurs when the ACD recorded in ACD block # 2 is reproduced, the state of ACA 213 shown in FIG. 8A is the same as that shown in FIG. 7A. 8B is a schematic diagram illustrating an example of ACD status information 411 included in the TDDS 410 according to the status of the ACD block in FIG. 8A. Referring to FIG. 8B, in order to indicate that the ACD recorded in ACD block # 2 of ACA 213 on the disc is valid (even if this acd cannot be reproduced), the positions bl25 and bl24 of ACD block # 2 in TDDS 410 are corresponding The bit in the medium will be changed to "10", so that the effective ACD recorded in ACD block # 2 can have a higher performance than the driving system that currently cannot reproduce the effective ACD recorded in ACD block # 2. Drive the system to regenerate. If the drive system with higher efficiency can regenerate the valid ACD recorded in ACD block # 2, the valid ACD can be moved to other normal blocks. In this case, when the disc is later loaded into another drive system, it is moved from ACD block # 2 to 21 20053 鼢 躱-the valid ACD of the normal block can be reproduced from the normal block instead of the ACD block # 2, which provides more convenient use of the disc. In particular, since the final TDDS will be recorded as the DDS in the DMA on the single-write disc during the completion of retaining the final state of the disc, the disc recording state is caused by an illegal change in ACA 213 on the disc or additional data Changes can be detected by comparing the ACD status information included in DSS with the actual status of ACA 213. The above comparison is possible because the ACD status information in TDDS 410 reflects the final status of ACA 213 and is copied to the DDS included in the DMA on the disc after the disc is completed. FIG. 9 is a structural diagram showing a rewritable information recording medium (rewritable disc 900) according to an embodiment of the present invention. Referring to FIG. 9, the rewritable disc 900 includes a lead-in area 91o, a data area 92o, and a lead-out area 930 in this order.

Public information 1021 includes ACD-ID 1023 and public information including formatting capability information 1024, spare area recording capability / reproduction capability information 1025 and UDA recording capability / reproduction capability information 1026. Fig. 10B is a schematic diagram showing an example of the ACA913 shown in Fig. 9. The second example shown in Fig. 10B is similar to the example of Fig. 10A, except that the common information 1011 includes the DMA recording capability information 1017 and the data area. The recording capability / reproduction capability information 1018 and the public information 1021 shown in FIG. 10B include the DMA recording capability information 1027 and the data area record. The recording capability / reproduction capability information 1028. In particular, the difference from the example shown in FIG. 10A is in In the second example, the DMA recording capability information 1017 and 1027 are included in the public information 23 20053ΐΜοο 1011 and 1012, respectively. However, even when the DMA recording capability information 1017 and 1027 are set to prohibit writing to the DMA, the DMA recording Capability information such as 7 and 1027 also does not include information about the DDS included in the DMA so that the ACD condition is recorded in the Jane. That is, DD on a rewritable recording medium S should be recordable.

When all the above-mentioned purposes are not required, the structure of the ACA in the above embodiment is the same for the single-write information recording medium and the repeatable information recording medium. When a cAD block is detected as defective during writing to the ACA or as a result of post-write verification, the ACD will be sequentially recorded in the blocks available in the ACA. During the re-initialization of the disc, the drive system will clear the ACD by recording a predetermined value (such as "00h" or "FFh") in the entire space of the existing ACD block, in which the ACD has been removed from the existing ACD block. Record on disc. In addition, during initialization and re-initialization, the drive system will record the ACD about the functions to be recognized by the drive system in the ACA and place the remaining unrecorded part of the ACA to a predefined value (for example, 00h, or "FFh ") To fill. FIG. 11 is a detailed structural diagram showing DMA # 915 according to another embodiment of the present invention, where DMA # 915 is provided together with an area in which ACD status information 1111 is recorded. Referring to FIG. N, DMA # 915 includes DDs 1110 and DFL 1120. DFL 1120 is an area that records information about defects that occur in UDA222 (such as the address of a defective block and the block address that replaces a defective block) for defect management. DDS 1110 is an area for recording disc management information for disc management. In particular, the ACD status information mi according to the embodiment of the present invention is recorded in the DDS 1110. 24 20053g ^ 2doc ACD status information 1111 contains the status of each ACD block in ACA 913. Referring to FIG. 11, 2 bits are allocated for status information about a single ACD block. Thus, the state information about 64 blocks in the defined ACA is recorded, and 64 * 2 = 128 bits are allocated to the ACD state information 1111. Accordingly, 16 bytes B0 ... B15 are allocated for status information about each ACD block in the ACA. The state of the ACD block on the rewritable recording medium can be represented by the four types in FIG. 5, however, the details of the four states can be different. As shown in FIG. 5, the state of each ACD block on the rewritable recording medium is represented by 2 bits, that is, "00 ,,,,, 〇1 ,,,, 10, or ,, U , To represent one of the four states. Bit "01" indicates that the ACD block is defective. More specifically, bit "01" indicates that the ACD block is detected as a defective state or a defective block with invalid ACD when recording ACD in the ACD block. . Bit "10" indicates that the ACD block had valid ACD but was detected as a defect when ACD was regenerated from ACA. Bit '' η "indicates that ACD has a valid ACD.

When using a rewritable disc, when the ACD in the ACD block recorded in the ACA of the disc is no longer valid, the ACD block will be overwritten with a predefined value (such as "00h" or "FFh") And the status information (that is, the bit indicating the status of the ACD block) will change to '' 〇〇, to indicate that the ACD block is available. Here, the ACD block is overwritten with "00h" or "FFh" to avoid invalid ACD regeneration from the ACD block when the status information of the ACD block cannot be read. In other words, to more reliably avoid the regeneration of invalid ACD, the ACD 25 20053 ^ ¾ block with invalid ACD is overwritten with a predefined value (for example, "00h" or "FFh"). s When the ACD recorded in the acd block needs to be updated during the use of the disc, the status information of the acd block with the old eight CDs in the DDS on the rewritable disc will be changed to ,, 01, to show * ACD The block has an invalid ACD 'and the updated ACD will be recorded in the available ACD block after being recorded in the aca on the rewritable disc. A detailed description of the ACD area will be given in conjunction with FIGS. 12A to 14B.

An example of block status information. FIG. 12a is a schematic diagram showing an example of the state of the ACD block shown in the ACA preview 913 of FIG. Referring to FIG. 12a, aca 913 includes 64 blocks, including acd block # 1 and ACD block # 2 with valid ACD and 62 blocks without data recorded therein but recordable data. FIG. 12B is a schematic diagram illustrating an example of ACD status information 1111 included in the DDS 1110 according to the status of the ACD block in FIG. 12A. Please refer to FIG. 12B ′ The DDS 1110 includes a 16-byte area to store acd-like information 1111 ′, which contains status information about the 64 blocks included in the ACA 913 shown in FIG. 12A. To indicate the ACD * block and # 2 with valid acd, bit "11" is recorded at positions M27 and bl26 as status information, and bit "11" is recorded at positions bl25 and bl24 as status information. In order to indicate that the other 62 blocks are not used but can be used for ACD recording, they are recorded at each position bl23 to b0 so that the status information about each 62 block can be represented by bit "00".

13A and 13B show ACD status information 1111 recorded in the DDS 1110 according to the updated ACD and the occurrence of a defective block. FIG. 13A 26 2050TO〇c is a schematic diagram showing an example of the state of the ACD block displayed in the ACA 913 of FIG. 12. Please refer to FIG. 13A, since the ACD recorded in ACD block # 1 is no longer needed, “00h” is used to overwrite ACD block # 1 in ACA 913 in FIG. 12A. In addition, when ACD about new functions is written When entering the ACD block # 3 to respond to the request or when a defect is detected at the same time as the verification result after writing, the block about the new function will be recorded in the subsequent block (that is, ACD block # 4). In other words, In ACA 913, ACD block # 1, ACD block # 2 is filled with valid ACD with, 〇hh, ACD block # 3 is a defective block and ACD block # 4 has a valid ACD. And the remaining 60 blocks are unrecorded and available. Figure 13B is a schematic diagram showing an example of the ACD status information 1111 included in DDS 111〇 according to the status of the ACD block in Figure 13A. Please refer to the figure 'as in ACA913's ACD block # 1 is overwritten with ,, 00h ,, so the positions bl27 and bl26 in DDS 1110 indicate that the bit of status information about ACD block # 1 will change to ,, 〇〇 ,, To allow ACD block # 1 to be used. Since there is no change in ACD block # 2, the status information about ACD φ block # 2 will be retained. Or verification of the results during the ACD block # 3 is detected as a defect after writing, so changes to ,, 〇1 "at the bit position bl23 and M22 will. Since the ACD block # 4 has a valid ACD about the new function, the bits indicating the status information about the ACD block # 4 in the positions bl21 and bl20 will be changed to "1Γ". FIGS. The error that occurred during the ACD block changes the ACD status information U11 recorded in the DDS 1110. Fig. 14 ^ is an example 27 showing the status of the ACD block in the ACA 913 shown in Fig. 9

A rewritable information recording medium having the state of ACA 913 shown in FIG. 13A can be loaded into the drive system, and the valid ACD basis when recorded in ACD blocks # 2 and 4 of ACA 913 respectively is included in the DDS shown in FIG. 13B Errors in the reproduction of ACD status information in 1110 can be corrected during reproduction. Since FIG. 14A shows the state of the block until an error occurs when the ACD recorded in ACD block # 2 is reproduced, the state of ACA913 shown in FIG. 14A is the same as that shown in FIG. 13A. FIG. 14B is a schematic diagram showing an example of ACD status information U11 included in the DDS 1110 according to the status of the ACD block in FIG. 14A. Please refer to FIG. 14B. In order to indicate that the ACD recorded in ACD block # 2 of aca 913 on the disc is valid (even if this aCd cannot be reproduced), the positions bl25 and bl24 of ACD block # 2 in DDS 1110 are corresponding. The bit in bit will be changed to 10, so that the effective ACD recorded in ACD block # 2 can be driven by a drive system having a higher performance than the drive system currently unable to reproduce the effective ACD recorded in ACD block # 2. To regenerate. If the drive system with higher performance can regenerate the valid ACD recorded in ACD block # 2, φ can move the valid ACD to other normal blocks. In this case, when a slice is later loaded into another drive system, a valid ACD moved from ACD block # 2 to a normal block can be reproduced from the normal block instead of ACD block # 2, thereby Provide more convenient use of discs.
