Abstract
It is intended to prevent occurrence of rotation lock waiting times when a simultaneous recording and reproducing operation is performed on a disc-shaped recording medium according to the ZCLV scheme. In a period when audio data of one data block are input to a recording buffer at a constant rate via an A/D converter, another data block that was input immediately before is recorded on and reproduced from an optical disc. Audio data constituting the reproduced data block are temporarily stored in a reproduction buffer and then read out at the constant rate and output via a D/A converter. A system controller performs control so that data blocks are recorded on the optical disc successively. As for a data block that is recorded in two adjacent zones, the system controller performs control so that the same data block that is read from the recording buffer, rather than the data block that has been recorded on the optical disc, is reproduced.
