Abstract
An optical compact disk drive includes a housing and a mounting seat with a disk-supporting tray that has opposite front and rear peripheral portions and that is formed with a recess between the front and rear peripheral portions and an elongated opening extending from a center of the recess to the rear peripheral portion. A pair of front air-communicating openings are formed in the front peripheral portion, and at least a rear air-communicating opening is formed in the rear peripheral portion. Air is permitted to flow from a bottom side to a top side of the disk-supporting tray through the front and rear air-communicating openings.
