Abstract: A controller of an optical disk apparatus moves a pickup head to a data area of an optical disk, and radiates a first DVD laser beam to the optical disk. The controller measures, as a first eccentricity amount, a number of beams, which have crossed a track on the optical disk, from a first tracking error signal from a head amplifier. The controller determines that the optical disk is a data-recorded first DVD optical if the controller determines that the measured first eccentricity amount is less than a predetermined reference value. The controller determines that the optical disk is a second DVD optical disk or the first DVD optical disk with a large eccentricity amount if the controller determines that the measured first eccentricity amount is greater than the predetermined reference value.
