Title:
DISK-SHAPED RECORD MEDIUM AND PRODUCING METHOD FOR SAME, DISK RECORDING METHOD AND DEVICE, AND DISK PLAYBACK METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO2007037537
Kind Code:
A9
Abstract:
To record specific information to a disk-shaped record medium and reproduce the recorded specific information without any influence on the error correction capability. Copy protection information (CPID) having an error correction code appended thereto, shuffled and otherwise treated is sent as a CPID bit block to an EDC rewrite circuit (14). The EDC rewrite circuit (14) rewrites an error detection code appended to user data in each sector in accordance with bit information in the CPID bit block. Thereafter, the data in each sector is scrambled, and an ECC block including a plurality of sectors is modulated with an error correction code and sync signal appended thereto. The modulated signal is recorded in a reserve area of a lead-in area of the disk-shaped record medium. During reproduction, CPID is restored based on the result of error detection of each sector.
