<P>PROBLEM TO BE SOLVED: To solve the problems: that disk rotating speed of an optical disk device is increased for high-speed data transfer rate and the air temperature inside the device rises due to increased generation of heat of a motor rotating and driving a disk or a driver driving the motor; that the generation of heat of a laser diode in an optical pickup, a laser diode driver driving the same, or the like is increased due to increase in the laser output for precise data recording/reproducing; and that the issue is the enhancement of heat dissipation of the optical pickup. <P>SOLUTION: In the optical disk device, besides a first through-part into which the optical pickup is inserted, a second through-part for inducing a flow from the lower side of a disk transfer member to the upper side is provided to the disk transfer member at the upstream side of the optical disk rotation with respect to the through-part at the disk outer circumferential side. <P>COPYRIGHT: (C)2007,JPO&INPIT |
