ABSTRACT:
An optical disk has regions in which sync signals are recorded. A data detection circuit detects data from a reproduced signal at a timing determined by a data detecting signal. A reproduced waveform of each sync signal is sampled at a first time point, and a first sample value representative thereof is generated. The reproduced waveform of each sync signal is sampled at a second time point different from the first time point, and a second sample value representative thereof is generated. The first and second sample values are compared, and a comparison signal representing a result of the comparing is generated. A phase of the data detecting signal is controlled in response to the comparison signal.
