Abstract:
1. A reproducing apparatus for reproducing channel data from a recording medium using interpolated timing recovery, comprising: a reading means for reading an information signal recorded on the recording medium; phase interpolating means for interpolating a phase of the information signal read by the reading means on the basis of a phase error signal sent as a feedback; first waveform equalizing means for equalizing a waveform of the information signal whose phase has been interpolated by the phase interpolating means while keeping the phase of the information signal fixed; phase-error-signal generating means for generating the phase error signal to be sent as a feedback to the phase interpolating means on the basis of the information signal whose waveform has been equalized by the first waveform equalizing means; second waveform equalizing means for equalizing the waveform of the information signal whose phase has been interpolated by the phase interpolating means without limiting a change of the phase; and decoding means for generating the channel data by decoding the information signal whose waveform has been equalized by the second waveform equalizing means.
