The DFL entry list 420 is a collection of DFL entries having defect status information regarding various blocks. The DFL entry list 420 includes a DFL entry #1 421, a DFL entry #2 422, . . . , through a DFL entry #N 423.
FIG. 5 is a structural diagram of a data format of a DFL entry #i 500 such as illustrated in FIG. 4.
Referring to FIG. 5, the DFL entry #i 500 includes status information 1 510, a physical address of a defect block 520, status information 2 530, and a physical address of a replacement block 540.
The status information 2 530 is information regarding the status of whether the replacement blocks in the spare area are usable. As such, by only indicating that the disc is re-initialized in the status information 2 530 of the DFL entry #i 500, without going through the verification operation after re-initializing the disc, re-initialization of the disc can be performed quickly. In addition, if the status information 2 530 of the DFL entry #i 500 of the block on which the data is to be recorded is set as the status information indicating the disc has been re-initialized when recording data after the re-initialization of the disc, a drive system knows that the disc has been re-initialized, and so can pad a predetermined amount of data in the rest of the block and record the data without going through an additional read-modify-write process, even if the host 3 commands to record data in a predetermined area of the block. Furthermore, the drive system knows that the data recorded in the block is invalid data if the status information 2 530 is set to indicate the disc has been re-initialized when a reproduction command output form the host 3 is received, and thus null data or a check message is immediately transmitted to the host 3.
FIG. 6 illustrates the status information 1 510 of the DFL entry #i 500 illustrated in FIG. 5.
Referring to FIG. 8A, the DFL entry for the block {circle around (1)} is the first entry listed in FIG. 8A. Since the block {circle around (1)} is the defect block with the replacement block, status information 1 is set to “1,” a physical address of the defect block is registered as “0010000h,” and status information 2 is set to “0” since the defect block is not yet re-initialized. Since the block {circle around (2)} is the defect block without the replacement block, status information 1 is set to “2,” a physical address of the defect block is registered as “10010100h,” and status information 2 is set to “0” since the defect block is not yet re-initialized. Since the block {circle around (3)} is the possible defective block, status information 1 is set to “3,” a physical address of the block is registered as “0010110h,” and status information 2 is set to “0” since the block is not yet re-initialized.
The DFL entry list illustrated in FIG. 8A changes into a DFL entry list as illustrated in FIG. 5B by re-initialization, which newly allocates the spare area #1.
Referring to FIG. 9A, a data area has only the spare area #1 allocated therein, and the data area includes the spare area #1 and a user data area. Blocks {circle around (4)}, {circle around (5)}, and {circle around (6)} are recorded at the end of the user data area, and block {circle around (7)} is recorded in the spare area #1. The block {circle around (4)} is a defect block and has a replacement block to replace the defect block. The block {circle around (5)} is a defect block that does not have a replacement block to replace the defect block. The block {circle around (6)} is a possible defective block. The block {circle around (7)} is a replacement block located in the spare area # 1 which cannot be used to replace another block.
Referring to FIG. 9B, if the blocks {circle around (4)}, {circle around (5)}, and {circle around (6)}, which were in the user data area before re-initialization, are included in the spare area #2 after re-initialization, DFL entries of the blocks {circle around (4)}, {circle around (5)}, and {circle around (6)} are changed into DFL entries having status information indicating all the blocks {circle around (4)}, {circle around (5)}, and {circle around (6)} have been re-initialized, together with status information indicating they are unusable for replacement. In addition, if the block {circle around (7)}, which was located in the spare area # 1 before re-initialization, is located in the user data area after re-initialization, a DFL entry of the block {circle around (7)} is changed into a DFL entry having status information indicating the block {circle around (7)} has been re-initialized, together with status information indicating it has a possible defect.
Referring to FIG. 10B, the DFL entry for the block {circle around (4)} is the second entry listed in FIG. 10B, the DFL entry for the block {circle around (5)} is the third entry in FIG. 10B, the DFL entry for the block {circle around (6)} is the fourth entry in FIG. 10B, and the DFL entry for the block {circle around (7)} is the first entry in FIG. 10B. Status information 1 of the DFL entries for the blocks {circle around (4)}, {circle around (5)}, and {circle around (6)} are all set to “5,” which indicates that they are blocks that cannot be used for replacement, by disc re-initialization, Status information 2, which indicates the state of re-initialization, of the blocks {circle around (4)}, {circle around (5)}, and {circle around (6)} are all set to “1” indicating that they have been re-initialized, and a physical address of the defect block moves to the location of a physical address of the replacement block. Status information 1 of the DFL entry for the block {circle around (7)} is set to “3,” which indicates it has a possibility of a defect, status information 2 is set to “1,” and a physical address of the replacement block moves to the location of a physical address of the defect block.
Referring to FIG. 13B, the defect blocks #3 through #5 with a possible defect included in the user data area even after re-initialization are the first DFL entry. That is, the first DFL entry has status information 1 set to “3,” which indicates the defect blocks #3 through #5 may have a defect, a physical address of the defect block registered as “0001010h,” which is a starting physical address of the sequential defect blocks, status information 2 set to “1,” which indicates re-initialization has been performed, and a physical address of a replacement block registered as “3,” which indicates the length of the sequential defect block.
