An optical disc medium (10) is provided with a data recording area (12) having the spiral recording track (11) and a lead-in area (13) composed of an embossed pit. In the lead-in area (13), information indicating a characteristic range of a signal detected by an optical head from a groove track is previously recorded. In accordance with a kind of the optical disc medium (10), even when the characteristic range of the signal detected by the optical head from the groove track is different, since the information indicating the characteristic range is previously recorded on the optical recording medium (10), tracking operation of the recording track can be performed under conditions within the characteristic range. Therefore, the tracking operation of the recording track (11) can be accurately performed to any kind of optical disc medium (10).
