Abstract
A micro-optical pickup head comprising a frame, a lens, a carrier, a lever and a focusing actuator is provided. The carrier is disposed in the frame for carrying the lens. The lever has an effort arm, a load arm and a supporting portion disposed between the effort arm and the load arm. The length of the load arm is larger than the length of the effort arm. The load arm is connected to the carrier. The supporting portion is fixed on the frame and used as a fulcrum of the lever. Besides, the focusing actuator is used for applying a force on the effort arm for enabling the carrier to move along a focusing direction.
