ABSTRACT:
The present invention provides an optical pickup actuator, in which a pair of lenses, e.g., BD lens and DVD lens, are loaded on one pickup to record/reproduce information on/from optical discs having various write capacities such as BD (Blu-ray disc), CD, DVD and the like, by which drive and system configurations can be simplified, and by which the facilitation of the system configuration and high sensitivity of the actuator are provided since there exist no sensitivity deviations of tracking and focusing between BD and CD or DVD actuators.
