PURPOSE: An optical pickup actuator is provided to improve tilt counter force to special disks by tilt-driving an actuator at a specific angle. CONSTITUTION: A plurality of first suspension wires(15A) and a plurality of second suspension wires(15B) have one ends soldered to coil PCBs(Printed Circuit Board,14) of a bobbin(12), and the other ends fixed at a PCB plate(19) after passing through a wire holder(13). The first suspension wires and the second suspension wires are different from each other in diameter. The bobbin is mounted with an objective lens(11) in the center, is wound by a focusing coil(16) and a tracking coil(17) on an outer peripheral surface, and is mounted with the coil PCB. A yoke plate(21) has a center hole(22) perforated in the center, and has an inner yoke(23) and an outer yoke(24) separated from each other.
