Abstract: An information recording medium of the present exemplified embodiment is configured by laminating a substrate having a predetermined thickness and a substrate having a predetermined thickness to each other. A film forming region including a recording region, a clamp region and a rib are formed on one surface of the information recording medium. A film forming region including a recording region, a clamp region and a rib are formed on the other surface of the information recording medium. On both surfaces, the components are formed in the order of the rib, the clamp region and the film forming region toward an outer peripheral side from an inner peripheral side.

Abstract: A lightweight radio/CD player for vehicular application includes a case and frontal interface formed of polymer based material molded to provide details to accept audio devices and radio receivers, as well as the circuit boards required for electrical control and display. The case and frontal interface are of composite structure, including an insert molded electrically conductive wire mesh screen that has been pre-formed to contour with the molding operation. The wire mesh provides shielding and grounding of the circuit boards via exposed wire mesh pads and adjacent ground clips.

Abstract: An optical disk player with improved opening and closing of a door, transport of a tray, and an improved pivoting structure of a chassis to pivot a turntable. The optical disk player includes: a body; a tray to move in and out of the body so as to transport an optical disk; a chassis installed to pivot inside the body; an optical pickup, which is installed to be able to move back and forth in the chassis, to record/reproduce information onto/from the optical disk that is rotatably placed on the turntable; a cover installed on a front of the body, the cover including: a door holder with an aperture through which the tray moves; a door to be able to slide along the door holder so as to open and close the aperture; and a cam driving device to activate the tray, to pivot the chassis, and to open and close the door by sliding.

Abstract: An apparatus to accommodate and load a disc cartridge in a drive includes a tray on which the disc cartridge is accommodated, a locking lever having a locking hook caught in a groove formed at a side wall of the disc cartridge when accommodated on the tray and which restricts/releases the disc cartridge using the locking hook. A sliding holder is slidably installed at the tray to prevent the disc cartridge from moving by pressing the disc cartridge restricted by the locking lever in one direction.

Abstract: A disc device, in which the recording medium can be inserted/ejected by a way of slot-in type no matter which type or shape the recording medium is. When the operator ejects the disc cartridge after it has been loaded in the disc device, by raising the holder, installed with the disc cartridge, the disc holder of the disc lever, supported by the carrier unit, will be in contact with the tip protrusion of the rotating member and will press upward the tip protrusion of the rotating member. Then, by the sliding member moving upward, the engaging portion, engaged to the acentric pins of the doors, will press the acentric pins upward and open the doors. Therefore, the disc cartridge can be ejected from the insertion hole without being obstructed.
