A position detector detects a relative position of an optical head to a recording medium, and on the basis of the thus-detected relative position, a position detection signal is generated in response to movement of a light beam over a predetermined distance. Then, in response to the position detection signal, a comparison is made between the number of track crossing counted for the predetermined movement distance on the basis of reception of reflection of the light beam, and a predetermined reference value for the predetermined movement distance. Then, track crossing count compensation data is generated which corresponds to a difference between the counted number of track crossing and the reference value, and the counted number of track crossing is corrected by use of such compensation data.
A track seek method for use with an optical information recording and reproducing apparatus which scans a light beam relative to an optical information recording medium in a direction across a plurality of tracks formed on the recording medium and counts the number of track crossing by the light beam on the basis of reception of reflection of the light beam from the recording medium so as to determine on which of the tracks the light beam is located, said track seek method comprising the steps of:
