Abstract

In an information recording medium for recording and reproducing data thereon on a sector-by-sector basis, the recorded data being managed as at least one file by using a file structure, the file structure includes unused space management information for identifying a used region and an unused region. At least one defective region is registered as an unused region in the unused space management information, the at least one defective region being a region on the information recording medium which is incapable of proper reproduction of the recorded data.

[0003] 2. Description of the Related Art

[0004] Optical disks are representative of information recording media having a sector structure. The trend for higher density and larger capacity in recent years has underlined the importance of the reliability of such disks. If a disk includes a sector in which information cannot be properly recorded or reproduced, such a sector is typically registered as a “defective sector” by an optical disk apparatus so that the defective sector will not be used thereafter, and another sector is substituted for that defective sector. This ensures reliability of the disk. Such a...
