ABSTRACT:
A tray locking apparatus of a disc drive to lock a tray on which a disc is placed and which is inserted into a main body of a disc drive. The tray locking apparatus includes a locking boss provided at the main body, a locking plate installed at the tray to slide and having a locking portion provided at one side thereof which is caught by the locking boss as the tray enters the main body, an elastic member to elastically bias the locking plate in a direction in which the locking portion is caught by the locking boss, and a driving mechanism to make the locking plate slide to be out of a position where the locking portion is caught by the locking boss when the tray is drawn. Thus, even when an external impact is applied, the locking state can be firmly maintained. Also, electric power consumed for the locking and unlocking operations is reduced.
