ABSTRACT:
In an information recording/reproducing apparatus, a data train of 1 and 0 as recording information is precoded to be converted into a recording data train. The recording data is recorded on a recording medium. A reproduction signal from the recording medium on which the recording data is recorded is obtained by partial response waveform equalization. The recording information has at least one data change from 0 to 1 or 1 to 0 within a predetermined period.
