Abstract:
An information reproducing apparatus (1) is provided with: a correcting device (18) for correcting waveform distortion occurring in a read signal corresponding to a long mark, of read signal (RRF) read from a recording medium (100); an amplitude limiting device (182) for limiting an amplitude level of the read signal in which the waveform distortion is corrected, by a predetermined amplitude limit value (L, −L), thereby obtaining an amplitude limit signal; and a filtering device (183) for performing a high-frequency emphasis filtering process on the amplitude limit signal, thereby obtaining an equalization-corrected signal.
