Abstract

An optical pickup actuator and a method thereof includes a bobbin having a lens to scan a laser beam on a track of a disc, a winding coil moving the bobbin on the track in focusing and tracking directions, and an integrated circuit board used as the bobbin using a printed circuit board manufacturing technology and integrally formed with the winding coil in a monolithic body. The bobbin used with the optical pickup actuator includes the printed circuit board, a plurality of tracking circuit patterns formed on both surfaces of the PCB, a plurality of focusing circuit patterns formed on the both surfaces of the PCB, a plurality of via holes formed on the PCB to electrically connect the tracking circuit patterns and the focusing circuit patterns, an objective lens mounting unit formed on the PCB, and a connecting pad through which a power is supplied to the tracking and focusing circuit patterns.
