Abstract: An optical pickup actuator which includes a base, a blade having an objective lens mounted thereon, a plurality of suspensions supporting the blade to be movable with respect to the base and forming an electroconductive path, and a magnetic circuit driving the blade according to a driving signal applied through the respective suspensions. The magnetic circuit includes a magnet fixed to the base, and a fine pattern coil installed on the blade at a position facing the magnet and having a track pattern coil, a focus pattern coil, and a tilt pattern coil independently driven by current applied through the suspensions and providing driving forces in a track direction, a focus direction, and a tilt direction of the blade.

Abstract: An optical pickup actuator including a multi-conductive suspension. The optical pickup actuator may include a base, a holder fixed to the base, a bobbin holding an object lens and having a plurality of driving coils, and a plurality of suspensions connected between the bobbin and the holder and movably supporting the bobbin toward the holder, wherein each of the suspensions may be a multi-conductive suspension including a flexible substrate and a plurality of wires, formed on the flexible substrate, applying currents to the coils.
