ABSTRACT:
A recording/reproduction of information is performed on a recording medium using a probe as follows. The relative movement between the probe and the recording medium along a track groove of the medium is performed on the basis of a predetermined drive signal. A voltage is applied to between the probe and the recording medium. A tunnel current flowing through the probe upon application of the voltage is detected so as to detect the track groove. A correction signal for correcting the drive signal is obtained on the basis of fuzzy deduction. The probe and the recording medium are driven relative to each other along the track groove in accordance with a drive signal corrected by the correction signal.
