ABSTRACT:
An information reproducing apparatus includes a reproduction clock generating device for generating a reproduction clock on the basis of a multivalue signal of a reproduction signal reproduced from an information recording medium, and a reproduction data detecting device for detecting the multivalue signal by using the reproduction clock, and for generating reproduction data synchronized with the reproduction clock. The apparatus further includes a first waveform equalizer for performing waveform equalization of the reproduction signal which is suitable for generation of the reproduction signal, and a second waveform equalizer, arranged independently of the first waveform equalizer, for performing waveform equalization of the reproduction signal which is suitable for detection of the reproduction signal.
