摘要： 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.

摘要： A lens position determination apparatus of an optical pickup includes a lens holder with a mounted lens, a base supporting the lens holder, and a pressing member. The base has an accommodation surface accommodating the lens holder and a pair of facing support walls on the accommodation surface. The pressing member is a bendable arm. A first elastic portion between arm end portions applies an elastic force in a direction in which the arm end portions closely contact the support walls. A second elastic portion connected to the arm presses the lens holder toward the accommodation surface to fix the lens holder position. The lens adjustment can be performed while the pressing force to fix the lens holder to the base is removed by bending the pressing member into a V shape to reduce frictional resistance of the lens holder with the base during the adjustment.
