ABSTRACT:
Guide members for guiding an optical pickup for movement in directions parallel to a diameter of an optical disk relative to the optical disk are formed of a metal, support members supporting the guide members on a chassis are formed of a resin, and heat transfer members formed of a metal are set in contact with the guide members and the chassis to achieve both the dissipation of heat generated by the optical pickup and the isolation of the optical pickup from vibrations. The guide support members attenuate vibrations propagating from the chassis toward the optical pickup, and heat generated by the optical pickup is dissipated through the heat transfer members into the chassis.
