Abstract

An optical pickup actuator having a printed circuit board and wire fixers for fixing one end of each of a the suspension. The optical pickup actuator includes coil connectors for connection with coils connectable to an external power source. The optical pickup actuator includes a blade having stoppers that are positioned to project from the blade between the wire fixers and the coil connectors so as to stop movement of the suspension wires during installation. The optical pickup actuator has an advantage in that a short circuit problem due to contact between the suspension wire and the coils is decreased, and, therefore, the optical pickup actuator facilitates mass-production.
