摘要： An optical pickup actuator includes a bobbin, support members, and a pair of magnetic circuits. An objective lens is mounted on the bobbin. The support members have first ends fixed on sides of the bobbin and second ends fixed to a holder placed on a portion of a base to allow the bobbin to move with respect to the base. The magnetic circuits are installed on two sides of the bobbin and on the base. Each magnetic circuit includes a tracking coil which moves the bobbin in a tracking direction, a plurality of focusing/tilting coils which moves the bobbin in at least one direction of a focusing direction and a tilting direction having a focusing component, and a magnet which faces the focusing/tilting coils and the tracking coil and have a polarized structure to move the bobbin in the tracking direction and at least one direction of the focusing direction and the tilting direction having the focusing component. Accordingly, the optical pickup actuator, which is capable of securing a tracking capacity and can become slimmer, can be obtained using the magnetic circuit including magnets having an improved polarized structure, a single tracking coil, and a plurality of focusing/tilting coils.
