Patent ID: 6944103

Claim:
An optical pick-up actuator comprising: a lens holder mounted with an object lens and attached with tracking and focusing coils, the lens holder being maintained in a suspended state; magnets adapted to generate a magnetic field interlinked with magnetic fields generated respectively by flows of current through the tracking and focusing coils, thereby allowing the object lens to be driven in focusing and tracking directions; and a tilt-compensating magnetic circuit which is located in a tracking direction interposing the lens holder therebetween and is adapted to generate a magnetic field interlinked with the magnetic field generated by the current flowing through the focusing coil, thereby automatically compensating a tilt depending on the current flowing through the focusing coil; wherein the tilt-compensating magnetic circuit is conducted to make a minus (−) tilting angle in its focusing-up operation and a plus (+) tilting angle in its focusing-down operation.
