Abstract
The present invention is related to a tray of an optical disc drive. In a tray according to one embodiment of the present invention, a flutter hole is formed in the middle of the tray providing space through which an optical pick-up moves toward an inner or outer circumferential area of an optical disc and a guide vane is formed to prevent contamination of the optical disc caused as grease spread on a lead screw of a sled motor for moving the optical pick-up moves according to air flow due to rotation of the optical disc. The guide vane can be formed only in a surface in which the lead screw is installed among two vertical side surfaces forming a boundary of a flutter hole of the tray and the guide vane can be formed at a position corresponding to an outer circumferential area of the optical disc.
