description The present invention provides a heat dissipation member for use in the optical disk drive. The present invention includes an outer frame and a chassis. The chassis has a drive module, a pickup module and two guide rods. A heat dissipation member is disposed on the pickup module and is in contact with a laser diode of the pickup module. When the drive module spins the optical disk at a rotational speed, an air flow is produced due to spinning of optical disk. A part of the air flow is directed to flow through the laser diode by the heat dissipation member so that excess heat generated by the laser diode is efficiently dissipated.
