Disclosed is a magnetic circuit operable in multiple axes in an optical pick-up actuator. The optical pick-up actuator includes: a lens holder (202) for receiving and moving an object lens (201) in a predetermined direction; a magnetic circuit having; a plurality of coils (205,206) series and parallel connected and attached to both sides of the lens holder; a yoke (203) and a magnet (204) faced with the coils, for generating and inducing different polarities in perpendicular directions. With such construction, the actuator moves the lens holder to tracking, focusing, tilting directions under control of a direction and intensity of a current by the magnetic circuit. |
