Abstract
An information reproducing apparatus () is provided with: a waveform shaping device () for performing waveform shaping on a read signal (R) read from a recording medium (), on the basis of a reference amplification factor; a correcting device () for correcting waveform distortion occurring in a read signal corresponding to at least a long mark, of the read signal on which the waveform shaping is performed; and a waveform equalizing device () for performing a waveform equalization process on the read signal in which the waveform distortion is corrected, the waveform shaping device arbitrarily increases the reference amplification factor.
