ABSTRACT:
An optical recording/reproducing system1reads a recorded signal written to a recording track of a recording medium3by light. The light is modulated by a drive signal on which a frequency signal is superimposed. The light is scanned along the recording track at a predetermined scan velocity. The optical recording/reproducing system1includes a computer13and an LD driver17that control, based on the scan velocity, a superimposed magnitude of the frequency signal on the drive signal.
