ABSTRACT:
A first error corrector performs error detection and error correction using inner codes on data subjected to an error correction coding processing with multiplication codes and a second error corrector performs error detection and error correction using outer codes on the data. A condition discriminator discriminates whether or not the data satisfies predetermined conditions, and a controller responds to the discriminator to prevent error detection and error correction using outer codes. Consequently, power for error detection and error correction is consumed only when sufficiently reliable data can be obtained by error detection and error correction using inner codes.
