ABSTRACT:
An information reproducing apparatus which reproduces information recorded on a medium includes an asymmetry correction circuit configured to correct an asymmetry of a signal read from a medium. The apparatus also includes a first high pass filter installed before the asymmetry correction circuit and configured to remove noise in the signal by a first cut-off frequency. The apparatus also includes a second high pass filter installed after the asymmetry correction circuit and configured to remove the noise in the signal by a second cut-off frequency, wherein the second cut-off frequency is higher than the first cut-off frequency.
