Abstract: A tray locking apparatus of an optical disk drive including a fixed frame and a tray that moves in and out of the fixed frame to load and unload a disk. The tray locking apparatus includes a first locking portion provided on the fixed frame, and a first lever, that has a second locking portion selectively coupled to the first locking portion, and moves between a coupling position and a releasing position. A first elastic member biases the first lever in a direction toward the coupling position. A switching unit installed at the tray locks the first lever at the coupling position by a magnetic force, and unlocks and moves the first lever to the releasing position by temporarily offsetting the magnetic force. A returning unit makes the first lever return to the coupling position from the releasing position when the tray moves out of the fixed frame.

Abstract: An optical disk drive includes a case, a tray which is slidably provided to the case and receives an optical disk, and a ground member which is electrically connected to the case and contacts one side of the optical disk as the tray slides in or out of the case. In the optical disk drive, by removing a static electricity remaining on the optical disk through the ground member, where the tray is loaded, foreign materials such as dust can be prevented from adhering to the optical disk. Accordingly, a stable and accurate optical signal processing can be guaranteed, thereby improving the reliability of the optical disk drive and the optical disk.

Abstract: An optical disc drive having a retractable and ejectable disc carrying tray. A compound pivot mechanism engages a turntable with a disc carried on the tray. The turntable is supported by a base chassis which pivots with respect to a main frame. A sub-chassis is pivotably connected with the mainframe and elastically coupled with the base chassis. A cam member on the main frame engages the sub-chassis to pivot the sub-chassis coincident with the tray being retracted into the main frame or ejected from the main frame. The sub-chassis in turn pivots the base chassis to engage or disengage the disc with the turntable. The tray accommodates discs having different diameters and comprises mechanisms for securing the disc while the disc is retracted into and ejected from the main frame.

Abstract: An optical disc driving apparatus requiring a fewer number of parts, simpler structure, less assembly cost, to thus result in a lower product price. The optical disc driving apparatus includes a base plate, on which a spindle motor and a pickup unit are mounted, is moved to optical disc loading and chucking positions together with a caddy by a physical force exerted to the caddy inserted into the deck base. The base plate is locked by a locking unit and positioned. In this situation, information is recorded and/or reproduced on/from the optical disc. In an ejection mode, the pickup unit is moved in a radial direction of the optical disc so that the base plate is unlocked and is moved to the initial position for unloading of the optical disc. Here, the physical force is a pressing force exerted by a user. Accordingly, the optical disc driving apparatus can be of a compact-size, and conveniently utilized as a caddy-type as well as a tray-type.
