Title: Information recording method and information reproduction method
Inventor: KIMURA NAOHIRO
IPC: G11B20/18
Filed: 2008-12-08
Abstract: When reproduction is performed from an optical disc of a format with which a reproduction device is not compatible, it is possible to prevent acquisition of an erroneous address causing a malfunction. Provided is recording method as follows. Encoding is performed by using an error correction code based on the Reed-Solomon code. For a codeword including a symbol C [i = 0, 1, 2,...n: n is an integer], a first conversion is performed to bit-invert a predetermined m pieces (1 < m < n: m is an integer) of symbols so as to generate conversion information. The conversion information is recorded in a first recording medium. The first conversion is set so that a distance between first information and second information is not smaller than 1/2 of a minimum free distance of the error correction code. The first information is obtained by subjecting the conversion information to an inverse conversion of the first conversion. The second information is obtained by subjecting the conversion information to an inverse conversion of the second conversion which is different from the first conversion.
