ABSTRACT:
An apparatus for phase correction of clock signal used for data reproduction employs reference clock signals recorded with the data to select the optimum phase increment for outside clock signals generated from preformed patterns on the recording medium. An apparatus for data reproduction compares recorded data sampled using outside clock signals phase corrected by the optimum phase increment with a threshold based on the reference clock signals to reproduce the recorded data with a high noise margin.
