ABSTRACT:
An optical disk device in which a moving state of a beam irradiating position is detected during the operation of an optical head in response to a jump signal, and in which an acceleration signal and a deceleration signal for said optical head are corrected based on a detection result for the subsequent jump operation, resulting in canceling an individual difference or the variation of the characteristic of the optical head.
