Abstract: A writing-system comprises a first and a second writing-device, and is connected to an information-processor-apparatus that obtains unwritten-data from the first and the second writing-devices when a notification is received, the notification indicating that the unwritten-data is generated while writing data on a recording-medium used by either of the writing-devices, wherein the first writing-device comprises a first writing-unit, when the unwritten-data is generated while writing data on a recording-medium, transmits to the information-processor-apparatus, dummy information for inhibiting the unwritten-data to be obtained by the information-processor-apparatus, and writes the unwritten-data to a memory-unit, the recording-medium and the memory-unit are included in a cartridge accommodated in the first writing-device, and the second writing-device comprises a second writing-unit that writes, on the recording-medium, the unwritten-data stored in the memory-unit when the cartridge is moved from the first writi

Abstract: The removable optical disc storage cartridge stores a plurality of optical disc media in a substantially stacked orientation for later extraction and presentation to a picker in an optical disc storage library. Each optical disc media is stored on a separate extractor that slides between a retracted and a stored position. An extractor tab, accessible outside or inside of the removable optical disc storage cartridge, is connected to each one of the extractors located within the removable optical disc storage cartridge. The removable optical disc storage cartridge further includes a security front door that operates between a closed and open position and further includes a locking element. The locking element may be operated by the picker or a release element contained on a magazine that handles multiple disc storage cartridges. The removable optical disc storage cartridge also includes seals to prevent dust from entering the removable optical disc storage cartridge.

Abstract: 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.

Abstract: The present invention provides a disc cartridge protecting member capable of closing a write and/or read aperture larger relative to the size of the disc cartridge and protecting a disc housed in the disc cartridge, such as optical disc used as an information recording medium. The disc cartridge protecting member includes an aperture closing plate which is to be fitted in, and to close, an aperture formed at one side of a disc cartridge having a disc housed rotatably therein and through which part of the disc is exposed to outside in a range between inner and outer radii thereof, an entry limiting portion supported on supports provided in the aperture formed in the disc cartridge to prevent the aperture closing plate from entering the disc cartridge, a cover plate extending on the other side of the disc cartridge opposite to the one side at which the aperture is formed, and a connecting plate to connect the base end of the aperture closing plate and that of the cover plate to each other.

Abstract: The invention consists of a combination of products including a optical data-media discs encased in a plastic cartridge or unincased in larger diameter from 5.25? to 9? discs with standard size and oversize versions with a sliding plastic or aluminum spring loaded doors to exclude dust, dirt, physical damage, and white color to reduce heat absorption, etc. Cartridge protective doors including spring operated side sliding and end sliding opening dust covers and fixed clear lens view window. The oversized discs provide security through non-interchangeability with standard sized discs. Also, the use of various shapes and sizes of holes through the case allow security through exclusion as does the cartridge itself.

Abstract: A system providing efficient cataloging and storage of data-storage devices. The system comprises a plurality of removable holders adapted to hold at least one of the data-medium-containing articles. Each holder is adjustably mounted within a support comprising three cylindrically shaped members. While engaged within the support, the holders are free to move independently along the cylindrically shaped members to permit holders to be added or removed from any position within the indexed plurality of stored holders. The system is modular and may be expanded in size and capacity. The system may be integrated within furnishings.

Abstract: The system includes a removable entertainment device including an information retrieval device. The information retrieval device is configured to receive removable storage media. The removable entertainment device includes a controller in electrical communication with the information retrieval device to retract the media into the information retrieval device when the controller receives a signal indicative that the removable entertainment device will be moved. Such signals may include a screen closure sensor, a movement sensor, or a player supported sensor.
