Abstract
An optical disk device includes an optical pick-up module including a rotating portion rotating an optical disk; a carriage mounting at least a light source and being provided movably within the optical pick-up module; and a cover having an opening formed thereon, a light being radiated from the light source through the opening toward the outside of the cover; and a tray supporting the optical pick-up module. The tray includes an optical disk attachment region portion opposed to the optical disk and an outside portion provided on an outside of the optical disk attachment region portion. The outside portion has a ledge along its portion adjacent to the circular perimeter of the optical disk. The optical disk, when mounted on the rotating portion, entirely lies between first and second planes, the first plane being defined by the surface of the cover and the second plane being defined by a first of opposing surfaces of the ledge, which first opposing surface is closer to the surface of the cover than is a second of the opposing surfaces of the ledge.
