A tray mechanism and a disk drive employing the tray mechanism. The tray mechanism includes a driving member rotatably coupled to a spindle motor; a pinion meshed with a rack provided at a surface of a tray to load the tray onto and unload the tray from a main frame; a pivotable plate pivotally provided at a shaft of the driving member, and having a connector which couples the driving member and the rack; and a limiting member provided on the main frame for limiting a pivotal range of the pivotable plate.

A damper and a disk drive using the clamper. The damper includes a body, a movable member inserted into a guide portion protruding from a center of the body so that the movable member is moved up and down along the guide portion, and having a plurality of opposed bosses, an elastic member, inserted into the guide portion under the movable member, for elastically biasing the movable member upward, and a stationary member, installed on an upper portion of the guide portion, for preventing the movable member from being released from the guide portion.

An optical disc drive including a clamping mechanism, which faces a turntable, supports a surface of a disc, and is rotated. The clamping mechanism includes a clamper, which has access to the disc by a magnetic force when a spindle motor has access to the disc so that the disc is not deviated from a mounting portion when clamping is not completely performed, and a return member, which allows the clamper to be spaced apart from the disc as the spindle motor is spaced apart from the disc.

Optical disc drive

An apparatus for automatically adjusting tilting of an optical disc drive, having placing parts, a plurality of height measurers, adjusters, a mirror disc, two mirror plates, an autocollimator, a photo detector, and a controller. The optical disc drive is placed on the placing parts. The plurality of height measurers measure heights of two portions of each of the pair of rails. The adjusters adjust the adjusting parts. The mirror disc is mounted on the turntable and spins. The two mirror plates are installed on the pair of rails. The autocollimator radiates parallel light beams onto the mirror disc and the two mirror plates. The photo detector detects focused points of the light beams reflected from the mirror disc and the two mirror plates and passing through the autocollimator. The controller calculates an amount of tilting from a distance between the focused points.

An optical disc drive includes a main body at which a spindle motor is installed. A tray installed at the main body is loadable/unloadable into/from the main body, and a disc holder is rotatable by the spindle motor when the tray is in a loaded position, and is joinable to a clamping hole of a disc so as to fix the disc.

Optical disc drive and method

A tray loading apparatus of an optical disc drive is provided. The tray loading apparatus includes a main frame, first rails that are installed in the main frame to guide a first tray on which a cartridge accommodating a disc is mounted so that the first tray slides into or out of the main frame, and second rails that are attachable to and detachable from the main frame and guide a second tray on which the disc is placed so that the second tray can slide into or out of the main frame. The tray loading apparatus further includes lockers that lock the second tray when the second tray is completely loaded into the main frame and disc guides that guide the outer circumference of the disc placed on the second tray. Accordingly, second rails can be separated from or coupled to a main frame to selectively load and unload a first tray on which a cartridge is mounted or a second tray on which a disc is placed.

A cartridge having a sensor hole to be opened/closed and a method and an apparatus for driving the same. To improve a problem that a cartridge receiving a DVD-RAM disc which has been once withdrawn therefrom performs the recording process under the same conditions as a bare disc, the disclosed cartridge has a unit for flexibly opening/closing the sensor hole in accordance with a result of a defect check, so that information processing process is greatly accelerated.

An automatic tilt compensator senses and automatically compensates for a disc deformation while an optical recording and/or reproducing apparatus operates. The automatic tilt compensator of an optical recording/reproducing apparatus has a disc deformation detecting section for sensing a deformation direction and a deformation degree of a disc seated and rotated on a disc rotation unit of a deck base and for outputting a predetermined signal, and a level adjustment section for elevating and lowering a pair of guide shafts movably supporting a pickup unit on the deck base while being operated by the signal from the disc deformation detecting section, to thereby adjust the level of the pickup unit corresponding to the deformation degree of the disc. According to this, the level of the pickup unit according to the deformation direction or the deformation degree of the disc can be automatically adjusted while the optical recording/reproducing device is operated. Accordingly, even when a deformed disc is inserted, since the level of the pickup unit is automatically adjusted according to the deformed disc, errors in recording and reproducing information caused due to the deformed disc can be remarkably reduced.

An adaptor includes a sensor hole to be open/closed, and a method and an apparatus drive the adaptor. The adaptor includes at least one sensor hole determining the size of a disc received in an adaptor body which is received via a disc holder. The disc holder includes an elastic press extended therefrom and elastically support the disc, preventing a movement of the disc until the disc holder is inserted into the adaptor body. Further, a release is disposed on the adaptor body to release the disc from the elastic press when the disc holder is inserted into the adaptor body. A method for driving the adaptor includes determining whether the sensor hole is open; and determining the type of device inserted into a disc drive. The type of drive inserted into the disc drive is determined by the adaptor accommodating an 8-cm disc when the sensor hole is open, while a cartridge accommodates a 12-cm disc when the sensor hole is closed. An apparatus for driving the adaptor includes a sensing switch to be selectively inserted into the sensor hole of the inserted adaptor to be turned on/off and transmit the corresponding signal regarding the open/closed state of the sensor hole to a microcomputer.
