ABSTRACT:
Tilt of an optical disk is detected and controlled by detecting a tilt zone border based on a zone correspondence table expressing a ZCLV zone of the optical disk and the tilt zone including a border corresponding to the border of the ZCLV zone. The deterioration of accessibility within the ZCLV zone at the time of tilt control is reduced by the tilt zone having a border corresponding to the border of the ZCLV zone.
