PURPOSE: An optical disk drive is provided to prevent vibration of a tray and optical disk due to the air flow by efficiently distributing air flow owing to the high speed rotation of an optical disk. CONSTITUTION: An optical disk drive(ODD)(300,400) includes a tray(30,40) and a top cabinet. The optical disk is put in the tray. Multiple bent holes(31,41) are formed in the rear part of a tray in which the optical disk is not put. The multiple bent holes distribute the air flow due to the high speed rotation of air. The multiple bent holes are arranged asymmetrically with reference to the center of a tray.
