Abstract:
An optical pick-up actuator comprising:a lens holder for housing an objective lens; a tracking system for moving the lens holder in a first plane; a focusing system for moving the lens holder in a second plane approximately perpendicular to the first plane; an elongated frame having first and second opposite ends, said frame comprising a support means connected to said first and second opposite ends for supporting said lens holder in a first suspended state with respect to the first plane; and a magnetic system in operational relationship with the first and second opposite ends of the frame, such that the magnetic system generates a magnetic field and at least the first end of the frame moves within the magnetic field to cause the frame to rotate about an elongated shaft running through the frame's first axis positioned between said first and second opposite ends of the frame, causing the support means to rotate the lens holder about the first axis to a second suspended state with respect to the first plane.
