Abstract:
The invention provides a method for controlling spherical aberration correction for an optical disk drive. First, a collimator lens is moved to a first target position for spherical aberration correction. A driving time of motion of the collimator lens is then calculated. A prohibiting time is then determined according to the driving time. The collimator lens is then prevented from moving until the prohibiting time elapses.
