A cartridge for an information recording medium includes a cartridge case, an opening cover, detachably mounted to a rear side opening of the cartridge case, for enabling the information recording medium to be withdrawn or inserted with respect to the cartridge case, and a holding unit for preventing movement of the information recording medium by supporting the information recording medium when the information recording medium is received and/or withdrawn into/from the cartridge case. The holding unit includes a pair of elastic pressure parts, elastically formed on the opening cover, for elastically supporting the information recording medium to prevent movement of the information recording medium when the opening cover is not attached to the cartridge case, and a release unit for releasing the pair of elastic pressure parts when the opening cover is attached to the cartridge case so that the information recording medium is rotatable in the cartridge case.

An apparatus and method of ejecting/loading a tray of an optical disk player using a digitizer connected to a personal computer (PC) or a keyboard, even though an EJECT button is not installed on a control panel of an optical disk includes using a optical disk control program stored in the optical disk player. The optical disk control program is to be installed in a personal computer (PC) and controls the ejection/loading of a tray of an optical disk player. If a predetermined key or key combination is entered through the computer, an EJECT or LOAD command is applied to the optical disk player in response to entering of the predetermined key combination via the optical disk control program. The tray of the optical disk player can be ejected/loaded using the keyboard or digitizer, and thus there is no need to install the EJECT button in the optical disk player.

A dynamic vibration absorber for a disk player includes a deck base, a deck plate movably disposed on the deck base to support a spindle motor that spins a disk, a mass body disposed around the deck plate, and a flexibly changeable connection member that connects the deck plate and the mass body. A dynamic vibration absorber including the mass and connection member reduces vibration generated when the disk spins using a reciprocal action of the mass body and the connection member relative to the deck plate.

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.

An optical recording/reproducing apparatus capable of using disc cartridges of at least two different sizes and/or a naked disc, on only one tray. The optical recording/reproducing apparatus is also capable of recording and/or reproducing information on/from one of the discs mounted on the tray by automatically detecting the disc cartridges and/or the naked disc positioned on the tray. The optical recording/reproducing apparatus has a case, a tray mounted to the case capable of being received and withdrawn into/from the case, and selectively accommodating disc cartridges of at least two different sizes, a support to support the disc cartridges positioned on the tray according to the size of the disc cartridges, a detection unit to detect the sizes of the disc cartridges positioned on the tray and the state of the discs accommodated in the disc cartridges, a rotating unit to rotate the discs in the disc cartridges positioned on the tray, and a recording/reproducing unit to record information on and/or reproduce the information from the discs rotated by the rotating unit.

An optical recording and/reproducing apparatus is capable of using a selected one of various types of recording/reproducing mediums including disc cartridges of at least two different sizes, a naked disc, and an adapter containing a disc having a diameter of 8 cm, by positioning the selected recording/reproducing mediums on one tray. The apparatus includes a tray mounted to the case and receivable into and withdrawable from the case. The tray accommodates the selected recording/reproducing medium so as to prevent movement of the recording/reproducing medium relative to the tray. A detecting section detects the size of the selected recording/reproducing medium positioned on the tray, and a state of a disc accommodated therein. A rotating section rotates the disc. An information recording/reproducing section records information onto, and/or reproduces information from, the disc rotated by the rotating section.
