A reproducing apparatus for reproducing channel data from a recording medium using the ITR includes a reading unit reading an information signal recorded on the recording medium; a phase interpolator interpolating a phase of the information signal read on the basis of a phase error signal sent as a feedback; a first waveform equalizer equalizing a waveform of the phase-interpolated information signal while keeping the phase of the information signal fixed; a phase-error-signal generator generating the phase error signal to be sent as a feedback to the phase interpolator on the basis of the information signal whose waveform has been equalized by the first waveform equalizer; a second waveform equalizer equalizing the waveform of the phase-interpolated information signal without limiting a phase change; and a decoder generating the channel data by decoding the information signal whose waveform has been equalized by the second waveform equalizer.
