A tray locking apparatus of a disc drive to lock a tray on which a disc is accommodated and which is inserted into a main body of the disc drive. The tray locking apparatus includes a locking pin provided at the main body, a locking lever rotatably installed at the tray and having a hook portion at one end thereof which is caught by the locking pin as the tray is inserted into the main body, an elastic member to elastically bias the locking lever in the direction in which the hook portion is caught by the locking pin, a driving mechanism to rotate the locking lever to escape from a position where the hook portion is caught by the locking pin when the tray is drawn, and a counter impact unit installed adjacent to the locking lever and having a moment to rotate in a direction opposite to that of the locking lever, so that when the locking lever is rotated by an impact in a direction to be unlocked, the counter impact unit rotates in the opposite direction and bumps against the locking lever. Thus, when an external impact is applied, the locking state of the tray can be firmly maintained.
