Abstract:
An optical disk device which records information on or reproduces recording information from an optical disk by use of optical head while the optical disk is chucked on a disk rotating mechanism and rotated, said optical disk device comprising:detecting means for detecting a tilt angle of the optical disk as it rotates;determining means for determining whether the tilt angle detected by said detecting means is set within a permissible range; andcontrol means for re-executing the chucking operation on the optical disk when said determining means determines that the tilt angle exceeds the permissible range,wherein, upon determining that the tilt angle exceeds the permissible range, said control means causes the optical disk to be released from the disk rotating mechanism, adjusts the disk rotating mechanism, and causes the optical disk to be re-chucked.
