| 20110119693 | CARTRIDGE DRIVE APPARATUS - A cartridge drive apparatus for a disc cartridge having upper and lower shells which are separatably joined to each other to form a cartridge body is disclosed, in which a accommodated disc is able to be inserted or ejected by separating the upper and lower shells vertically. The cartridge drive apparatus includes a cartridge holder which, by inserting the cartridge body, has an upper holder supporting the upper shell and a lower holder supporting the lower shell, and a holder moving mechanism which separates the upper holder and the lower holder of the cartridge holder to separate the upper shell and the lower shell and thus is able to allow the disc to be inserted or ejected. | 05-19-2011 |
| 20110134732 | OPTICAL RECORDING MEDIUM, OPTICAL RECORDING MEDIUM DRIVING APPARATUS, AND OPTICAL RECORDING MEDIUM DRIVING METHOD - An optical recording medium driving apparatus includes an optical pickup which irradiates first and second laser lights from one object lens with respect to an optical recording medium having a bulk layer and a tilt detection surface; a focus control portion that performs the focus control relative to each predetermined position of the optical recording medium in regard to each of the first and second laser lights; a tracking control portion that controls the position of the object lens to perform the tracking control of the first and second laser lights relative to the optical recording medium; and a tilt control portion. | 06-09-2011 |
| 20110225602 | DISC CARTRIDGE - A disc cartridge includes upper and lower shells making up a cartridge body, and with the lower shell, a first-rectangular plate, and disc holders making up the side wall of the cartridge body provided to first-side edges of the first-rectangular plate, and also slidably supporting a disc are provided, and second-side edges which face each other are opened, with the upper shell, a second-rectangular plate, standing wall members provided to third-side edges of the second-rectangular plate, making up the front and rear faces of the cartridge body, and a dividing wall provided to fourth-side edges are provided, and with the disc holders, an disc insertion/ejection opening from the second-side edges is provided to one edge, and a push-out opening for a disc push-out member is provided to the other edge, and when the shells are combined together, the second-side edges are closed, and are opened when the shells are separated. | 09-15-2011 |
| 20110296445 | DISC CHANGER - A disc changer includes: a disc cartridge having a case body in which a plurality of disc-shaped recording media are storable by being arrayed in the axial direction of the center axis, and an information input medium to which at least information relating to pitch between disc-shaped recording media and the number of stored disc-shaped recording media is input; a disc holder configured to hold the disc cartridge, a portion of which is moveable in the center axial direction of the disc-shaped recording media; and a movement mechanism including an encoder, configured to determine a stop position in the center axial direction of the disc holder based on information input to the information input medium. | 12-01-2011 |
| 20110296446 | DISC CHANGER - A disc changer includes a disc cartridge having an insertion hole, a case body into which the disc cartridge is inserted, having first and second shells which can be separated in which a plurality of disc-shaped recording media are storable by being arrayed in the axial direction of the center axis, and a lock lever for locking the shells in a connected state; and a disc holder to hold the inserted disc cartridge, including an unlocking piece which unlocks locking between the shells by being inserted into the insertion hole when the disc cartridge is inserted into the disc holder to press the lock lever, and a restricting lever supported by the unlocking piece, including a restricting portion engaged with the case body when the unlocking piece is inserted into the insertion hole, so that locking between the shells is unlocked, the restricting lever restricting movement in the extracting direction. | 12-01-2011 |
| 20110296449 | DISK CARTRIDGE - A disk cartridge includes a case body that can house a plurality of disk-shaped recording media and is joined or separated by making a first shell contact with/separate from a second shell in an axial direction, and a lock lever that is rotatably supported and locks the first shell and the second shell in a joining manner, in the inside of the case body. A disk inserting/ejecting slot is formed, a supporting shaft is provided to the case body, the lock lever includes a supported part, a lock part, and a lock-release part, the first shell is provided with an open/close panel that includes an insertion hole, an insertion protrusion part that is inserted into the insertion hole of the open/close panel is provided to an end part of the lock-release part, and an end face of the insertion protrusion part is formed as an inclined face. | 12-01-2011 |
| 20110296450 | DISC CARTRIDGE - A disc cartridge includes a case body in which a plurality of disc-shaped recording media can be stored being arranged in the axial direction of a central shaft and which includes a first shell having a base face portion parallel to a recording face of the recording medium and a second shell having a basal plane portion parallel to the recording face, which move toward or away from each other in the axial direction, thereby being combined with or separated from each other, wherein the second shell has a pair of side face portions protruding in the same direction from both end portions of the basal plane portion and situated facing each other, a thin-walled portion is formed at a central portion between the side face portions in the basal plane portion, and a bridge member which is attached to span the side face portions is provided. | 12-01-2011 |
