Referring to FIG. 6, the status information 1 510 includes five states, �1,� �2,� �3,� �4,� and �5.�
The status information �1,� �2,� and �3� indicate the status of blocks in the user data area, and the status information �4� and �5� indicate the status of blocks in the spare area.
The status information 2 530 is not illustrated in FIG. 6, but, for example, the disc is re-initialized if the status information 2 530 is set to �1,� and the disc is not re-initialized, or is used after re-initialization, if the status information 2 530 is set to �0.� If the status information 2 530 is set to �0,� valid data is recorded in the block. If the status information 2 530 is set to �1,� valid data is not recorded in the block since the block has been re-initialized.
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.
Referring to FIG. 8B, the DFL entry for the block {circle around (1)} is the first entry listed in FIG. 8B, the DFL entry for the block {circle around (2)} is the second entry in FIG. 8B, and the DFL entry for the block {circle around (3)} is the third entry in FIG. 8B. Status information 1 of the DFL entries for the blocks {circle around (1)}, {circle around (2)}, and {circle around (3)} are all set to �3,� which indicates that they are possible defective blocks due to disc re-initialization, and status information 2 of the DFL entries for the blocks {circle around (1)}, {circle around (2)}, and {circle around (3)} are all set to �1,� which indicates that they have been re-initialized.
Referring to FIG. 10A, the DFL entry for the block {circle around (4)} is the first entry listed in FIG. 9A. Since the block {circle around (4)} 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 (5)} 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 �0010100h,� and status information 2 is set to �0,� since the defect block is not yet re-initialized. Since the block {circle around (6)} 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.
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.
FIGS. 11A through 11C illustrate three DFL entries when the status information 1 is set to �3,� which indicates a block may have a defect.
Referring to FIG. 11A, status information 1 of the DFL entry is set to �3,� which indicates the block may have a defect, a physical address of a defect block indicates a physical address of the possible defective block, status information 2 is set to �0,� which indicates re-initialization is not yet performed, and a physical address of a replacement block is registered as �1,� which indicates the block is a single block.
Referring to FIG. 12A, defect blocks #1 through #5 with a possible defect are sequentially disposed in the user data area. The defect blocks #1 through #5 with a possible defect form the sequential defect blocks. The starting address of the sequential defect blocks is shown as �0001000h.�
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.
The blocks #1 and #2, which are included in the spare area after re-initialization, are the second and third DFL entries illustrated in FIG. 13B. The second DFL entry has status information 1 set to �5,� which indicates an unusable block, status information 2 set to �1,� which indicates re-initialization has been performed, and a physical address of a replacement block registered as �0001000h.� The third DFL entry has status information 1 set as �5,� which indicates an unusable block, status information 2 set to �1,� which indicates re-initialization has been performed, and a physical address of a replacement block registered as �0001001h.� The sequential defect blocks in the user data area can be shown as a single DFL entry, but a DFL entry for each replacement block exists even if the replacement blocks in the spare area are in a sequence.
One method is to verify predetermined blocks from the starting block of the sequential defect blocks by �verification after recording,� and generating a DFL entry for each of the verified blocks depending on where the blocks exist (i.e., in the user data area or the spare area) after newly allocating the spare area. That is, first, �verification after recording� is performed, and if it is determined that a block in the user data area has a defect even after the spare area is newly allocated, a DFL entry according to the determination is registered. But if it is determined that the block does not have a defect, a DFL entry of the block does not need to be registered. Also, if the block in the newly allocated spare area is determined to have a defect, a DFL entry having status information indicating the block is an unusable replacement block is registered, and if the block is determined not to have a defect, a DFL entry having status information indicating the sequential block is a usable replacement block is registered.
Referring to FIG. 15A, status information 1 of the DFL entry is set to �3,� which indicates a possible defective block, a physical address of a defect block indicates a physical address of the possible defective block, status information 2 is set to �0,� which indicates re-initialization has not been performed, and a physical address of a replacement block has registered therein a predetermined value �FFh� to indicate the length of the sequential defect blocks is unknown.
Referring to FIG. 15B, the DFL entry remains the same as the DFL entry of FIG. 15A, and status information 2 also remains set to �0,� as described above.
