Abstract

A digital signal reproducing apparatus is capable of reproducing digital signals with an accurate sampling clock synchronized with the phase of a read signal. A sequence of predetermined sampled values are detected from sampled values produced by A/D converting a read signal. In this sequence of predetermined sampled values, a difference value of two samples produced at timings spaced apart by a predetermined interval from each other is calculated in order to generate a sampling clock having the phase corrected on the basis of the difference value.
