Abstract: In an optical pickup actuator performable a tilting operation which operates an object lens so as to follow the center of signal tracks of an optical disc, an optical pickup actuator performable a tilting operation includes a plurality of damper holders separately fixed to both sides of a base, a lens holder placed between the plurality of damper holders and having an object lens for reading and writing information on a disc, suspension support means separately connected between both sides of the lens holder and the plurality of damper holders so as to support the lens holder as two sides one-stage support structure, and magnetic operating means separately installed at the lens holder and the base and operating the lens holder so as to follow an optical disc, accordingly an optical pickup actuator performable a tilting operation in accordance with the present invention can perform not only a translational motion in a tracking direction and a focusing direction but also a tilting motion in a radial direction a

Abstract: Disclosed is an optical pick-up actuator including a tilt-compensating magnetic circuit adapted to conduct a tilt compensation depending on current flowing a focusing coil attached to a lens holder maintained in a suspended state. The tilt-compensating magnetic circuit includes magnets or electromagnets for generating a tilt-compensating magnetic field. Alternatively, the tilt-compensating magnetic circuit is configured to allow focusing and tracking magnets and a tracking coil to be movable toward the outer periphery of a disk, to which the optical pick-up actuator is applied. In either configuration, the tilt-compensating magnetic circuit generates a tilt-compensating magnetic field depending on the current flowing through the focusing coil. In accordance with the optical pick-up actuator of the present invention can conduct a tilt compensation depending on a control current flowing the focusing coil at the point of time when a focusing control is required.

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.
