OPTICAL DISK DEVICE AND METHOD OF DRIVING THE SAME

摘要

An optical disk device including: an optical pickup which includes a collimator and an object lens for focusing parallel light beams from the collimator at a position on an optical disc; a collimator driver unit which moves the collimator in an optical axis direction; a movement mechanism driver unit which moves the optical pickup in the radial direction; and a drive control unit which performs an adjustment process for adjusting the positions of the object lens and the collimator. In the adjustment process, the drive control unit causes the collimator driver unit to operate after stopping the movement mechanism driver unit or a spindle motor, and causes the movement mechanism driver unit or the spindle motor to re-start operating after the collimator driver unit finishes moving the collimator.

1. An optical disk device comprising:
an optical pickup which (i) includes a collimator for collimating light from a predetermined light source to parallel light beams, and an object lens for focusing the parallel light beams from the collimator at a position on an optical disc, and (ii) reads data recorded on the optical disc; a collimator driver unit configured to move the collimator in an optical axis direction; an optical pickup movement unit configured to move the optical pickup in a radial direction of the optical disc; and a drive control unit configured to perform an adjustment process for adjusting positions of the object lens and the collimator, wherein, in the adjustment process, the drive control unit is configured to cause the collimator driver unit to operate after stopping the optical pickup movement unit, and cause the optical pickup movement unit to re-start operating after the collimator driver unit finishes moving the collimator.
