Abstract

An optical pickup assembly includes an optical pickup unit (OPU), a thermally conductive plate, and a flex circuit. The flex circuit is mounted atop the plate. The OPU is also mounted atop the plate through a cutout of the flex circuit. Alternatively, the flex circuit is mounted below the plate and the OPU is mounted atop the plate. The optical pickup assembly further includes an actuator arm. The OPU is mounted on the actuator arm with a portion of the plate contacting the actuator arm.
