Abstract
An optical pickup actuator and an optical recording and/or reproducing apparatus and method using the same. The optical pickup actuator includes a blade, a plurality of suspensions, first and second coil members, and a magnet member. An objective lens is placed on one side of the blade. Each of the suspensions is coupled at one end to the blade and fixed at the other end to a holder provided at one side of a base, such that the suspensions movably support the blade. The first and second coil members are installed on the base to be separated from each other, with the magnet member being installed on the blade between the first and second coil members.
Claims23
An optical pickup actuator, comprising:
- a blade with an objective lens;
- a plurality of suspensions coupled at one end to the blade and fixed at another end to a holder, provided at one side of a base, such that the suspensions movably support the blade;
- first and second coil members installed on the base, separated from each other;
- and
- a magnet member installed on the blade between the first and second coil members.
An optical recording and/or reproducing apparatus, comprising:
- an optical pickup having an actuator for driving an objective lens, and movably installed in a radial direction of a recording medium, and records and/or reproduces information to/from the recording medium;
- and
- a controller controlling a focusing servo and a tracking servo of the optical pickup, wherein the optical pickup actuator includes:
- a blade with an objective lens;
- a plurality of suspensions coupled at one end to the blade and fixed at another end to a holder, provided at one side of a base, such that the suspensions movably support the blade;
- first and second coil members installed on the base, separated from each other;
- and
- a magnet member installed on the blade between the first and second coil members.
An optical pickup actuating method, comprising:
- moving a blade, including a lens, in tracking and/or focusing directions;
- and
- driving a coil system, separated from the blade, such that an interaction with a magnet on the blade controls the moving of the blade in the tracking and/or focusing directions.
