ABSTRACT:
In recording/reproduction of information, a probe is used to scan the surface of a recording medium in which a recording bit is formed and the recording bit is detected by comparing a signal detected via the probe with a predetermined threshold value. A signal detected within the recording surface is normalized on the basis an amplitude value of a signal detected on a portion where no recording bit is present by the probe.
