Abstract
An optical pickup actuator for driving, by a magnetic driving unit, in a focusing direction, a tracking direction, and a tilting direction, a bobbin on which an objective lens is disposed and which is movably supported by suspension wires, including at least one damping member is disposed at a position where greatest changes in the optical pickup actuator occur when driving the bobbin in the focusing direction, the tracking direction, and the tilting direction, so that a size of a second resonant peak is reduced.
