Abstract: A method for copy protection includes providing audiovisual or audio data stored in sectors of a record carrier having a file system, and providing additional or modified data to be stored in further sectors. The method includes generating a first file of the file system referencing at least a part of the sectors and none of the further sectors, so when the first file is rendered by a playback device, the data is reproduced which is included in the part of the sectors. The method also includes generating a second file of the file system being another file than the first file and referencing at least a part of the sectors and further referencing at least one of the further sectors, such that when the second file is rendered by the playback device the part of the sectors and the at least one of the further sectors are reproduced.

Abstract: The magazine includes a rail installed on its bottom surface approximately parallel to an insertion/extraction direction, the rail including a plurality of stepped portions formed at a side surface thereof. A device body includes: a lock lever installed rotatably within the same plane as the bottom surface of the magazine, the lock lever including one portion located in a space below the magazine and another portion located beside the magazine; a spring which urges in a direction in which the rail is installed so that a portion of the lock lever located in a space below the magazine is engaged with the stepped portion; and an accessor which moves beside the magazine along the insertion/extraction direction. The lock lever engaged with each stepped portion is released in such a way that the accessor rotates the lock lever in an opposite direction to an urging direction of the spring.

Abstract: Disclosed is a data cartridge library system capable of using a data cartridge holder. The data cartridge holder comprises a bottom and side walls wherein the side walls are attached to the bottom wall at one end and form a terminal edge at another. The terminal edge defines an opening through which a plurality of data cartridges can be inserted and removed from the data cartridge holder. In one embodiment, the data cartridge holder can comprise at least a pair of hook-like structures on opposite sides of the data cartridge holder to engage a mounting structure in the data cartridge library. The data cartridge holder can further be adapted to be covered by a dust cover wherein the dust cover can be capable of engaging the data cartridge holder in a first and second position without impeding either the insertion or extraction of a data cartridge or the engagement with the mounting structure of the library.

Abstract: To provide a disc changer capable of working without any malfunctions in spite of a reduced number of switches, it includes a mode-detecting mechanism having means for identifying an operation, cams respectively operated by powers supplied from a first and second motors, each cam provided with said identifying means, sensors for detecting said identifying means moving according to the operation of said cam, each composed of a set of a light-emitting element and a light-receiving element, a control section for receiving operation signals detected by said sensors to control the operation of the disc changer, and transmission gears for driving said cams, said transmission gears interlocking with a transporting gear meshing with a rack of said main tray for carrying the main tray out with the subtray put thereon.

Abstract: A library apparatus can reduce number of motors to be incorporated and can reduce number of parts for simplification of construction for contributing to down-sizing of the apparatus and reducing a cost. The library apparatus of a storage media reads and/or writes information from and in a storage medium housed in a cartridge by withdrawing a desired one of a plurality of cartridges housed within a magazine which is loaded in an apparatus body, by cartridge loading and unloading means and loading the withdrawn cartridge in medium drive means. The cartridge loading and unloading means performs loading and unloading of the magazine to the apparatus body.
