Abstract: An electronic device includes a peripheral wall defining an opening, a frame defining an internal receiving space, a tray, a stopping piece, a button, and an elastic piece. The tray receives a storage device and is slidably received in the receiving space. The stopping piece is fixed between the opening and the frame. The stopping piece blocks the tray when the tray is wholly received in the receiving space. The button is connected to the stopping piece and configured to drive the stopping piece to release the tray when the button is pressed. The elastic piece pushes the tray to pass to be partly exposed out of the opening when the stopping piece releases the tray.

Abstract: A CD Card for packaging card like information and digital information in the basic dimensions (length and width) of a business, credit or collectors card. The CD Card is made up of one, two, or three major components. The first component is a small compact disc with dimensions small enough to be contained within the typical dimensions (length and width) of a business card, credit card, or collectors card. The second component is a container shaped like a business, credit, or collectors card in length and width, but with a depth large enough to hold the small compact disc and adapter (if required) discussed subsequently. The third component is an adapter designed to position the small compact disc of the first and third embodiments of the present invention correctly in standard CD drives. A second embodiment of the small compact disc may not require an adapter or case.

Abstract: An adapter A1 made of a synthetic resin includes an annular frame 1 having an outside diameter of 12 cm, a disk receiving section 2 provided continuously on a lower portion of an inner edge of the frame 1, and a pair of disk pressing sections 3 and 3 provided continuously on an upper portion of the inner edge of the frame 1. The disk receiving section 2 is provided with a circular opening 4 for causing an information recording area of a disk to face an optical reader of a disk player. A disk press-contact projection 7 formed so that a projection height is gradually increased in a disk rotation direction Y is provided on a lower surface of each disk pressing section 3. This adapter A1 can securely install a non-circular optical disk even if the optical disk has a slightly different size, and an installation operation of the non-circular optical disk can be easily performed.

Abstract: A disk drive system having a disk-shaped disk storage medium and a disk drive for accessing the disk storage medium including a media cartridge of the same shape as that of the disk storage medium to which not less than one small-sized storage medium is attachable, and an access unit provided in the disk drive for accessing the small-sized storage medium attached to the media cartridge.

Abstract: An optical disk adapter can position a deformed CD at a predetermined position in a disk-transferring tray by a very simple operation, and is simple in structure and easy in manufacture. At the central portion of an adapter main body (1a) having an external periphery with the same diameter as a 12 cm-CD, a positioning true circular central aperture (2) in which a square CD (C1) with an 8 cm-diagonal length can be fitted in a non-restricted state is provided. The center of this positioning true central aperture (2) is concentric with the center of the adapter main body (1a). The adapter main body (1a) is provided with a rotation prevention protrusion (3) against the disk-transferring tray (71) at the lower surface thereof and a disk clamper passing dented portion (4) at the upper surface thereof.

Abstract: An optical disc drive with a memory medium accessing module to access an optical disc and a memory medium. The optical disc drive includes a main body, a tray, a memory medium transformer and a connector. The tray is disposed on the main body. The tray supports the optical disc when the optical disc is used. The memory medium transformer is placed on the tray to load the memory medium electrically connected thereto. The connector is disposed in the main body. The tray is received in the main body and the connector is electrically connected to the memory medium transformer when the memory medium is used and the tray supports the memory medium transformer.

Abstract: A holder for holding at least one compact disc includes structure that releasably engages part of a peripheral edge of the disc, such that a continuous, flush, and planar upper surface is formed when the holder is engaged with the disc.

Abstract: A disk cartridge includes a case, substantially rectangular in shape, provided with a disk-shaped rotatable recording medium therein, the case including a plurality of windows through which the recording medium is exposed and a recording or reproducing head is inserted when recording or reproducing, and shutters provided for the plurality of windows respectively, that are capable of opening and closing so as to cover the plurality of windows when recording or reproducing is not performed, a first window and a second window of the plurality of windows being formed on one surface, and a width of the first window in an opening and closing direction of the shutters being wider than that of the second window. With this arrangement, it is possible to provide a disk cartridge capable of adopting for both a driving device for a small-sized disk and a driving device for a large-sized disk.
