An optical disc drive includes an electro-conductive chassis, a tray, a bezel and an electro-conductive sheet. Wherein, the electro-conductive chassis has an opening portion. The tray is disposed inside the electro-conductive chassis for carrying an information storage medium and can move into and from the electro-conductive chassis, and the bezel is disposed at a front edge of the tray. In addition, the electro-conductive sheet is disposed between the front edge of the tray and the bezel, and substantively covers the opening portion of the electro-conductive chassis. As the tray stays inside the electro-conductive chassis, the electro-conductive sheet is in contact with the electro-conductive chassis. Consequently, the electro-conductive sheet is able to reduce the electromagnetic interference (EMI) generated during the operating of the optical disc drive. Further, the electromagnetic wave leakage damaging human health is also prevented.
