ABSTRACT:
A header in which an address signal has been recorded is provided on the disc for every predetermined sector interval. Recording data is arranged in an error correction encoding block and the error correcting process is performed. The error correction encoding block is divided into a plurality of portions in a predetermined direction, thereby forming sectors S1, S2, S3, . . . . The data of each sector is recorded subsequent to the header. Upon reproduction, the header is detected and the data is reproduced for every sector. One of the error correcting processes is performed in the reproduced data in the sectors S1, S2, S3, . . . . In the case where errors cannot be corrected by the error correcting process in the reproduced data in the sector, the error correction block including the sectors S1, S2, S3, . . . is reproduced and the error correcting processes are performed in the sequences in two directions.
