Abstract
A disk drive includes a disk tray disposed within a casing for receiving an optical disk thereon, a clamp-holding seat disposed above the disk tray and having a clamp opening, a clamp disposed within the clamp opening in the clamp-holding seat and projecting downwardly from the bottom side thereof, a protrusion structure disposed on the clamp-holding seat, a resilient structure disposed on the clamp-holding seat opening opposite to the protrusion structure, and a spindle motor disposed below the disk tray for rotating the disk once the spindle motor is moved upward via the reading opening to a reading position, where the disk is sandwiched between the clamp and the spindle motor.
