ABSTRACT:
An optical pickup actuator reducing an access time to a disc, and an optical recording and/or reproducing apparatus using the same. The optical pickup actuator includes a base, a wire holder on one side of the base, a bobbin on which an objective lens is placed, first and second yokes, suspension wires, and a magnetic driving unit for driving the bobbin in focusing and tracking direction. The first yoke is between one side of the bobbin and the wire holder, and the second yoke is on the other side of the bobbin. A damping member is inserted into the first yoke. One end of each of the suspension wires is fixed to the wire holder, and the other end movably supports the bobbin. Accordingly, an access time, an important performance characteristic in a high-speed optical recording and/or reproducing apparatus is reduced due to an improvement of a damping effect.
