ABSTRACT:
An objective lens actuator includes a lens holder for receiving an objective lens, a first micro-actuator, and a second micro-actuator. The first micro-actuator is connected to the lens holder and is configured for driving the objective lens along a substantially radial direction of an optical disk. The second micro-actuator is connected to the lens holder and is configured for driving the objective lens substantially along a direction perpendicular to the optical disk.
