  • Method and apparatus for controlling spherical aberration correction for an optical disk drive
    Patent number: 7839734
    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.

  • OPTICAL STORAGE APPARATUS AND CONTROL CHIP FOR ACCESSING AN OPTICAL DISC AND METHOD THEREOF
    Publication number: 20100034061
    Abstract: An optical storage apparatus includes an optical pickup head, a drive module, a spherical aberration compensator, and a controller module. The drive module is coupled to the optical pickup head for performing a predetermined operation associated with the optical pickup head. The spherical aberration compensator is coupled to the optical pickup head for performing a spherical aberration compensation upon the optical pickup head. The controller module is coupled to the drive module and the spherical aberration compensator for controlling the drive module to perform the predetermined operation during a first period of time and the spherical aberration compensator to perform the spherical aberration compensation during a second period of time. The first period of time overlaps the second period of time.
