Recording apparatus enabling replacement of disk cartridge

A disk cartridge and a disk recording and/or reproduction apparatus including a protrusion group which is made up of a plurality of protrusions and formed within a case housing a disk or within a housing in which a disk is loaded. Accordingly, the protrusions induce the flow of air generated during the rotation of the disk to serve as a force generated by variations in flow velocity and pressure. Therefore, foreign materials can be effectively removed from the surface of the disk using the flow of air without a separate cleaning apparatus.

An optical pickup apparatus for an optical disk drive records or reproduces data on or from an optical disk, includes an optical head section including an object lens focusing an incident light on the optical disk, a slider on which the object lens is mounted, wherein the slider floats over the optical disk by an air bearing generated between the optical disk and the slider, a bobbin on which the slider is mounted, and a flexure disposed between the slider and the bobbins elastically supporting the slider. A driving unit drives the slider in a tracking direction and a focusing direction. In the above construction, the slider floats over a recording surface of the optical disk due to an air bearing and a near field between the object lens and the optical disk can be controllably maintained.

A tray guide mechanism for an optical disc drive guides a backward and forward movement of a tray installed to slide into and out of a housing made of a lower case and an upper case. The tray guide mechanism includes guide rails installed to slide into and out of both sides of the upper case, a guide rail supporting unit installed at both sides of the lower case, to prevent the guide rails from deviating from a backward and forward moving path, and rail combiners formed at both sides of the tray in a moving path of the tray, and combined with the guide rails to slide into the guide rails. The tray guide mechanism also includes a forward moving distance limiting unit to limit a moving distance of the tray and the guide rails in a direction to which the tray and the guide rails project to prevent the tray from detaching from the housing. The tray guide mechanism also includes vertical and horizontal restrainers to prevent vertical and horizontal movement of the tray. The guide rails are shaped such that the rail combiners are inserted thereinto, and includes rails which slide into and out of the rail combiners while remaining in contact with the rail combiners. The guide rails also include rail covers which are fixed to outer sides of the rails and slide into and out of the lower case while being in contact with the lower case. The tray guide mechanism is configured such that a guide rail is installed in contact with a rail and a rail cover, and thus is strengthened to firmly support the tray and is installed in a narrow space of the compact optical disc drive. Also, the tray guide mechanism includes the vertical and horizontal restrainers that prevent vertical and horizontal vibration or swaying of the tray.

Tray guide mechanism for an optical disc drive

A tray locking apparatus of a disc drive to lock a tray on which a disc is placed and which is inserted into a main body of a disc drive. The tray locking apparatus includes a locking boss provided at the main body, a locking plate installed at the tray to slide and having a locking portion provided at one side thereof which is caught by the locking boss as the tray enters the main body, an elastic member to elastically bias the locking plate in a direction in which the locking portion is caught by the locking boss, and a driving mechanism to make the locking plate slide to be out of a position where the locking portion is caught by the locking boss when the tray is drawn. Thus, even when an external impact is applied, the locking state can be firmly maintained. Also, electric power consumed for the locking and unlocking operations is reduced.

Tray locking apparatus of disc drive

An actuator loading/unloading device includes a block unit disposed at a base of a disc drive to be positioned outside a disc, a lamp member positioned on the block unit so that the lamp member is lifted from or lowered down on the block unit, an actuator being parked on the loading/unloading device by constraining a side end portion of a swing arm of the actuator during loading/unloading of the actuator, a stopper to restrict a lifting range of the lamp member, and a lifting/lowering unit to lift or lower the lamp member between the block unit and the stopper. The lifting/lowering unit includes a magnet inserted into a bottom surface of the lamp member, and an electromagnet inserted into a top surface of the block unit, facing the magnet. As a result, the actuator is stably parked on the disc drive having a compact structure where the actuator cannot be completely escaped from the disc during unloading of the actuator.

Actuator loading/unloading device for disc drive

A disc cartridge for receiving a disc includes a case which accommodates the disc and at least one centering spring which prevents deviation of the disc in the case. Thus, a gap in which the disc moves in the disc cartridge is restricted so as to reduce a length in which a disc clamp of the disc contacts a disc clamp guide inside a disc drive system. Accordingly, the height of the disc clamp is reduced so as to reduce the thickness of the disc cartridge and miniaturize the disc cartridge.

Disc cartridge

A tray locking apparatus of a disc drive to lock a tray on which a disc is accommodated and which is inserted into a main body of the disc drive. The tray locking apparatus includes a locking pin provided at the main body, a locking lever rotatably installed at the tray and having a hook portion at one end thereof which is caught by the locking pin as the tray is inserted into the main body, an elastic member to elastically bias the locking lever in the direction in which the hook portion is caught by the locking pin, a driving mechanism to rotate the locking lever to escape from a position where the hook portion is caught by the locking pin when the tray is drawn, and a counter impact unit installed adjacent to the locking lever and having a moment to rotate in a direction opposite to that of the locking lever, so that when the locking lever is rotated by an impact in a direction to be unlocked, the counter impact unit rotates in the opposite direction and bumps against the locking lever. Thus, when an external impact is applied, the locking state of the tray can be firmly maintained.

Tray locking apparatus used with a disc drive

An actuator of a disc drive having a shock damping device includes an electro-magnet disposed on a cover of the disc drive, a magnetic material disposed on a load beam of the actuator, opposite to the electro-magnet, and a driving control portion controlling a driving of the electro-magnet by detecting an vibration of the load beam towards and away from an optical disc that is caused by an external shock. When the load beam is vibrated by the external vibration or shock to the disc drive, electricity is supplied to the electro-magnet, securing the load beam to the cover until the vibration ceases. Accordingly, even when there is external vibration or shock applied to the disc drive, possible damage to the disc or the actuator can be minimized or prevented.

Actuator of disc drive having shock damping device

A disc cartridge having a disc to record information and a case to accommodate the disc includes a cleaning unit installed inside the case and selectively contacting or being separated from the disc depending on a flow of air generated during a rotation of the disc, so that the cleaning unit removes foreign material adhering to a surface of the disc when contacting the disc. Since cleaning is automatically performed depending on the flow of air, inconvenient manual operation is not necessary. Furthermore, since the cleaning unit does not deviate from a disc area, miniaturization of the disc cartridge or disc recording and reproducing apparatus is possible.
