摘要： 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.

摘要： 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.

摘要： 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.
