Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To suppress increasing a processing time of error correction even if quantity of information of error correction codes for intrinsic ID is increased in an information protecting system recording ID being intrinsic for a medium and using the intrinsic ID as a key of security. SOLUTION: Two kinds of error correction codes for intrinsic ID of which processing time for error correction are different are recorded in a medium A as a recording form being referable to a file system for a first error correction code having a short processing time and as a recording form being not referable to the file system for a second error correction code having a long processing time. Normally error correction for intrinsic ID is performed by using the first error correction code, only when the first error correction code is not correct, error correction is performed by using the second error correction code.
