Patent abstract
According to the present invention, whether recoding pits are larger or smaller than diffraction limit is determined. Then, a signal process suitable for processing of the recording pits larger than the diffraction limit and a signal process suitable for processing of the recording pits smaller than diffraction limit are divided to divisionally perform equalizer processing. The respective signals subjected to the divisional processing are synthesized to obtain a processed output signal. A reproduction signal with reduced impact of intersymbol interference is thus obtained.
