Abstract

To provide an error correction circuit which can perform error correction of both ECC blocks of the present DVD and the next generation DVD with common constitution. This error correction circuit has: a conversion part 21 in which ECC block data, this sector number, and a sync-frame number are received for each frame, a discrimination signal indicating whether the ECC block data conform to a first standard or it conforms to a second standard of which the recording density is higher than the above is received, when the discrimination signal indicates the second standard, region numbers A, B of the frame are converted from the sector number and the sync-frame number and outputted; a judging part 22 judging existence of an error by calculating an error correction code included in the ECC block data based on a position of the ECC block data recognized by receiving the sector number, the sync-frame number, and this region number; and error correction parts 24, 25, 26 correcting this error data when the judging part judges that an error exists.
