Patent ID: 8289824

Claim:
An optical pickup apparatus, comprising: a plurality of laser beam sources to emit laser beams for recording and/or reproducing information on a disk which is a recording medium; a laser driving circuit to drive and control the laser beam sources; an object lens actuator including an object lens for guiding the laser beam to a predetermined position on the disc; an optical pickup housing to accommodate therein the laser beam sources and the laser driving circuit within the optical pickup housing; and an upper cover of said optical pickup apparatus provided between an upper surface of the optical pickup housing and the disc in a direction of an optical axis of the object lens of said object lens actuator, wherein the upper cover is distinct from the optical pickup housing; and wherein the upper cover is mounted to the optical pickup housing with a predetermined air gap there between, and the laser driving circuit is fixed in a state in which thermal conductivity is secured with respect to said upper cover of said optical pickup apparatus, and wherein said upper cover does not obstruct the laser beam sources in a direction of an optical axis of the object lens of said object lens actuator; and wherein said upper cover is connected to the optical pickup housing at portions thereof other than a portion thereof located between the plurality of laser sources and the laser driving circuit.
