Abstract
A playback clock generating circuit whereby the effect of a local flaw may be diminished to enable high-precision clock reproduction. During reproduction of a reference area, a signal processor 2 calculates a phase error of the playback clocks CK by a clock generation processor 2A based on sampled values of the playback signals of the reference pattern A/D converted by an A/D converter 1. During reproduction of a data area, the signal processor sends a phase correction signal derived form the phase error to a clock generator 3 for correcting the phase of the playback clock CK generated by the clock generator 3.
