Claim:
An ejection device for a slot-in disk drive, the slot-in disk drive comprising a driving motor for rotating a gear set, the ejection device comprising: a sliding component, the sliding component driven by the gear set moving forward and backward inside the slot-in disk drive; a loading bar driven by the sliding component for pushing an optical disk; an unloading bar, driven by the sliding component for pushing the optical disk with the loading bar; and a block disposed on a contact end of the unloading bar for pushing the optical disk so that a distance between a center of a small size optical disk and a contact end of the loading bar exceeds a predetermined distance being over half a radius of a central hole of the small size optical disk when the unloading bar pushes the small size optical disk outwardly; wherein the slot-in disk drive loads and unloads the optical disk once so as to drive the loading bar to push the small size optical disk further outward after the unloading bar backs to an initial position.
