Paper Abstract

In an optical pick-up head, the objective lens actuator is a key component used to move the objective lens to the exact position for focusing the laser spot on the disc recording layer and keeping the laser spot following certain track on the disc. In order to be used in a compact pick-up head for high density drives, the objective lens actuator must be compact and controllable in focusing, tracking, and radial tilt directions. In this paper, an electromagnetic three-axis-controllable actuator with a novel structure was designed and verified. The read tests done by using a pick-up head with the actuator designed in this work proved the feasibility of this design.
