  • Patent number: 7372785
    Abstract: A spherical aberration compensation actuator and an optical pickup system are provided. The spherical aberration compensation actuator mounts an element for compensating a spherical aberration and operates to a single-axis direction on an optical path using electromagnetic force. The optical pickup system includes a laser diode, an object lens, a spherical aberration compensation actuator, an optical path changer, and an optical detector. The spherical aberration compensation actuator is installed on an optical path between the laser diode and the object lens and includes a lens holder having a spherical aberration compensation element for compensating a spherical aberration generated due to light passing through the object lens and operating in an optical-axis direction using electromagnetic force.

  • Publication number: 20030112719
    Abstract: An optical pickup actuator is provided to improve a driving property in a radial direction. In accordance with the optical pickup actuator of the present invention, radial coils are wired in predetermined locations of both side parts of a lens holder. In addition, ends of existing fixed members are curved and protruded outside. Magnets for radial coil are attached to the protruded part. Therefore, a mass to be applied to the lens holder is minimized and an excellent driving property is ensured in focusing and tracking directions as well as in a radial direction, thereby simplifying the structure and decreasing the cost.
