摘要： A reproduction apparatus is provided for reproducing information recorded on an information recording medium. The information recording medium includes a data area for recording user data; and a defect management area for recording a defect list for managing N number of defect areas existing in the data area, where N is an integer number satisfying N≧0. The defect list includes two or more blocks and a header located at a fixed position in the defect list. The defect list further includes N number of defect entries, located subsequent to the header, including position information on the respective positions of the N number of defect areas; and an anchor located subsequent to the defect entries.

摘要： A recording method for recording, on a write once type information recording medium, management information representing a recording state of the write once type information recording medium is provided. The information recording medium includes data including a first synchronization signal. The information recording medium has a second synchronization signal pre-recorded by cutting. The recording method includes the steps of (a) performing a recording operation for recording the management information at a predetermined position of the information recording medium based on the first synchronization signal; (b) determining whether the recording operation in step (a) is normally terminated or not; and (c) when the recording operation in step (a) is not normally terminated, performing a recording operation for recording the management information at the predetermined position of the information recording medium based on the second synchronization signal.

摘要： 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.

摘要： An information recording medium includes a disk information area; a user area including a plurality of sectors; and a spare area including at least one sector which, when at least one of the plurality of sectors included in the user area is a defective sector, is usable instead of the at least one defective sector. The spare area is located radially inward from the user area. A physical sector number of a sector to which a logical sector number “0” is assigned, among the plurality of sectors included in the user area and the at least one sector included in the spare area, is recorded in the disk information area.
