Abstract
A molded coil device includes a coil comprised of a plurality of turns of a conductive material through a plurality of planes and an integral body comprised of an insulating and nonmagnetic material burying the coil. The coil is first formed and thereafter is sintered/pressed with the insulating and nonmagnetic material to form the integral body. The molded coil device is advantageously applied within an optical pickup actuator of an optical disc drive.
