Apparatus, method and program for waveform equalization on a read signal obtained by reading the record data recorded on a recording medium |
摘要 |
An information reproducing apparatus (1) is provided with: an offset adding device (19-1, 19-2) for adding an offset value (OFS) which can be set to be variable, to a read signal (RRF) read from a recording medium (100); a correcting device (18) for correcting waveform distortion occurring in a read signal corresponding to a long mark, of the read signal to which the offset value is added; and a waveform equalizing device (18) for performing a waveform equalization process on the read signal in which the waveform distortion is corrected. |
