Summary:PROBLEM TO BE SOLVED: To provide a waveform equalizer and a recorded information reproducing apparatus in which jitter never be caused in a reading signal read from a recording medium and an S/N can be improved. SOLUTION: An amplitude level of a filter processing reading signal obtained by performing filtering processing for the reading signal read from the recording medium is limited by an amplitude limit value being smaller than amplitude of the filter processing reading signal corresponding to recording data being short successively to the minimum reversal interval, and waveform equalization is performed by performing filtering processing for this amplitude-limited amplitude limit reading signal.
