Information recorded medium, information recording/reproducing method, and information recording/reproducing device

摘要

The present invention has as an object to accomplish reliable data reproduction in a data reproducing apparatus in which servo operation easily becomes unstable in an unrecorded disc area, and provides a data storage medium whereby the highest address of the reproducible data area is obtained by the optical disc drive, and reproduction is possible using only a normal READ command, without providing a physical area in the volume space. Address information (181) for an integrity information area (111) allocated in the first overrun extent in the volume space is recorded to a lead-in area (101) reproducible by an optical disc drive. As a result, when a disc is inserted to a data reproducing apparatus, address information for the first integrity information in the volume space is recorded to the lead-in area, or the highest address of the reproducible data area is obtained by the data reproducing apparatus following the integrity information, preventing the optical disc drive from accessing an unrecorded disc area.
