ABSTRACT:
A spherical aberration compensation actuator and an optical pickup system are provided. The spherical aberration compensation actuator mounts an element for compensating a spherical aberration and operates to a single-axis direction on an optical path using electromagnetic force. The optical pickup system includes a laser diode, an object lens, a spherical aberration compensation actuator, an optical path changer, and an optical detector. The spherical aberration compensation actuator is installed on an optical path between the laser diode and the object lens and includes a lens holder having a spherical aberration compensation element for compensating a spherical aberration generated due to light passing through the object lens and operating in an optical-axis direction using electromagnetic force.
