Abstract
The magnitude (Ga) of an impact applied to a lens holder is constantly monitored based on an output of an impact sensor. When it is determined that Ga exceeds Gth, focus servo is released, and the lens holder is provided with a force to make it move away from a disk. Upon recheck of Ga, when it is determined that Ga is now equal to or less than Gth, the force having been provided to the lens holder is cancelled, and the focus servo is resumed.
