When subcodes included in a CD format are reproduced, jitter is removed when the subcodes are synchronized with signal data. The data is connected together by using the subcode data to prevent interruptions of sound and pictures. An error correction unit performs error correction processing for signal data reproduced (read) from a CD. A memory stores the signal data whose error is corrected and a data output unit reads out the signal data stored in the memory according to a reference clock. A subcode detection/jitter removal unit detects subcode data reproduced from the CD and outputs the subcode data to the memory in synchronism with outputting of the signal data whose error is corrected by the error correction unit, to thereby remove jitter.
