Abstract
A plurality of error correction circuits connected in series include a calculator circuit that corrects the codeword when the determination results of a determination circuit indicate that the error correction circuit at the present stage is to correct the codeword, and a determination circuit at a subsequent error correction apparatus determines whether the error correction circuit at the subsequent stage is to correct the codeword when the determination results of the determination circuit indicate that the error correction circuit at the present stage is not to correct the codeword.
