PURPOSE: An optical pickup actuator is provided to uniform the weights of front and rear parts of a blade, thereby improving the performance of a test according to driving of an actuator. CONSTITUTION: A yoke plate(10) has a wire holder(20) on one side of a top side. A plurality of suspension wires(30) are installed so that one ends of the plurality of suspension wires pass through the wire holder. An asymmetrical blade(40) is installed by the suspension wires and has an objective lens(42) on one side. An assembly(48) is installed inside the asymmetrical blade, and a tracking coil(46) and a focusing coil(44) are installed at the assembly. An insertion groove(41) is formed in the center between a width direction inside of the asymmetrical blade and the assembly. A weight(50) is installed in the insertion groove for matching front and rear centroid of the blade.
