Abstract
A disk tray is mounted in an optic disk drive for supporting an optic disk. The disk tray forms a circular recess for receiving the optic disk therein. Openings are defined in the disk tray along a circumference of the circular recess for forming air passages communicating upper and lower sides of the disk tray whereby when the optic disk is rotated at a high speed during the operation of the optic disk drive, pressure difference induced between the upper and lower sides of the disk tray is reduced by air flowing through the air passages.
