ACTUATOR DEVICE OF OPTICAL PICK-UP AND ITS MANUFACTURE

摘要

PROBLEM TO BE SOLVED: To improve efficiency in manufacturing work of an actuator device of an optical pick-up work, and to permit a better management of manufactured actuators. SOLUTION: A metallic mold used at the time of molding an object lens supporting member 1 is provided with a core to form a coil, and a focus coil 2 and a radial coil 3 are arranged on the core beforehand. The coils and the object lens supporting member are molded in one body by molding the object lens supporting member 1 with the metallic mold provided with the coils wound around the core.
