Abstract
An optical disk drive includes a case, a tray which is slidably provided to the case and receives an optical disk, and a ground member which is electrically connected to the case and contacts one side of the optical disk as the tray slides in or out of the case. In the optical disk drive, by removing a static electricity remaining on the optical disk through the ground member, where the tray is loaded, foreign materials such as dust can be prevented from adhering to the optical disk. Accordingly, a stable and accurate optical signal processing can be guaranteed, thereby improving the reliability of the optical disk drive and the optical disk.
