ABSTRACT:
An optical disk drive driving an optical disk includes a vibration detecting part for detecting a vibration due to rotation of the optical disk, an operation part for calculating a rotational speed of the optical disk at which the vibration detected by the vibration detecting part is equal to or close to a given threshold value which is a critical point for tolerable vibration, and a control part for controlling the optical disk to be rotated at the rotational speed calculated by the operation part.
