Abstract: A removable hard disk module is provided which is mainly applicable to a server system. The removable hard disk module includes a server rack and a hard disk removable enclosure which is detachable form the server rack. The server rack has at least one pair of accommodation slots with threads formed on an inner wall thereof. The hard disk removable enclosure defines a space to accommodate a hard disk and has a threaded engagement portion disposed therein corresponding to the threads. When the hard disk removable enclosure is inserted into the accommodation slots, the threaded engagement portion is contacted with the threads, and the hard disk removable enclosure is moved alone to the threads through the threaded engagement portion, thereby the hard disk removable enclosure is moved into and fixed within the accommodation slots of the server rack.

Abstract: An optical disc access control and storage apparatus containing a rotating plate for storing discs thereon and rotating the same, a first disc-pushing mechanism for moving a disc along its radial direction from the rotating plate to a second disc-pushing mechanism wherein the second disc-pushing mechanism has a positioning slot for positioning the disc, an auxiliary-fixing mechanism for fixing the disc positioned in the positioning slot, a seizing mechanism for seizing the disc, a rotating mechanism fixed to the seizing mechanism for rotating the seizing mechanism, a coordinate-displacing mechanism connected to the rotating mechanism for controlling the horizontal and vertical positions of the seizing mechanism and at least one disc player for receiving the disc released from the seizing mechanism.
