Abstract
PURPOSE:To shorten an access time by starting a tracking by a converging means when the relative speed of the oscillation of the converging means goes to zero after a rough access. CONSTITUTION:An optical head 3 is moved in a direction of the radius of a disk 1 by a first moving means 13, the converging means 6 is moved according to a detecting signal from a photodetector 8 by a second moving means and followed and controlled in a movement to the track of the disk 1 by a control means 16. At the time of moving the optical head 3 by the first moving means 13, the control by the control means 16 is stopped and at the time of stopping the optical head 3, the relative speed of the converging means 6 and the corresponding track is detected according to the detecting signal from the photodetector 8 and at the time of detecting the relative speed of zero, the control by the control means 16 is started. Thereby after the rough access, the oscillation of an objective lens is contracted to start the tracking and access speed can be increased.
