Abstract
Error correction code (ECC) encoding is performed by using a first ECC encoding means to add a first check code to each of a number of first code groups included in a code sequence. Additionally, a second ECC encoding means is employed to add a second check code to each of a number of second code groups. The second check code is extracted from a predetermined number of successive first code groups in the code sequence.
