Abstract
A CD-ROM reproduction apparatus which allows error correction for both audio data and CD-ROM data using a single error correction circuit with a miniaturized size. The CD-ROM reproduction apparatus comprises, in addition to the single error correction circuit, an error syndrome monitoring circuit to monitor the error syndromes generated upon error correction processing and to detect presence or absence of an error. Depending upon whether error correction is performed for audio data or for CD-ROM data, the internal connection of the error correction circuit is switched so that the error correction circuit performs error correction for audio data or CD-ROM data. Error correction calculation by the error correction circuit is not performed for audio data or CD-ROM data discriminated to include no errors by the error syndrome monitoring circuit.
