Abstract
An optical disc player wherein an amount of jitter in a write clock as opposed to a read clock is detected by a jitter counter, a the write clock is counted by a reference counter for the number of frames, the jitter amount is added/subtracted to/from the count output by an adder/subtractor, an offset for the predetermined number of frames is given to a result of the addition/subtraction to generate a subcode synchronizing signal completely synchronized with the read clock. The subcode synchronizing signal is outputted through an output determining circuit only when a reproduction subcode synchronizing signal is found matching by a match detector with the count output of the reference counter twice successively. The device can correctly perform sound linking even for software having successive fixed patterns and perform sound linking without error even if reproduction data at sound linking point is processed with previous-value hold or interpolation.
