An optical disc drive includes a tray, a frame, and a traverse module. The tray includes a circular disc loader adapted to support an optical disc therein, a feeding slot, and two gaps at opposite sides of the tray. The frame includes two side walls with a plurality of stoppers provided thereon, a tray loader, two protrusions provided on inner surfaces of the side walls, and two ventilation grooves between the protrusions and the side walls. When the optical disc drive is used as a vertical tray loading disc drive, an optical disc is loaded in the disc loader of the tray. The protrusions are located at the gaps of the tray, and prevent the disc from falling out of the disc loader. Airflow around the rotating disc is smoothly expelled out of the tray via the gaps and the ventilation grooves. Noise produced by the airflow is reduced accordingly.
