摘要:
An information reproducing apparatus (1) is provided with: an amplitude limiting device (151, 152) for obtaining an amplitude limit signal (RSLIM) by limiting an amplitude level of a read signal (RRF) read from a recording medium (100) on the basis of a predetermined amplitude limit value; and a filtering device (158) for obtaining an equalization-corrected signal (RSH) by performing a high-frequency emphasizing and filtering process on the amplitude limit signal, the amplitude limiting device individually sets each of an upper limit (L1) and a lower limit (L2) of the amplitude limit value.
