摘要： This data security arrangement provides a significant level of data security in an automatic magnetic tape cartridge library by isolating the actual data from the control of the data retrieval process. This isolation is accomplished by the use of a plurality of architectural devices that dissociate control and data. The data written on the magnetic tape cartridges cannot be accessed by the library modules. The library modules are not electrically connected to the tape drives or the data bus that connects the tape drives to the host computer. In addition, library software on the host computer emulates an operator's console and intercepts all tape mount commands generated by the host computer. The library software translates these commands into control signals to activate the library module to retrieve a designated magnetic tape cartridge and load this cartridge into a tape drive. Thus, the data retrieval apparatus is separate from the library control apparatus. The library module is unaware of the identity of the data stored on the magnetic tape cartridges and the host computer is unaware of the existence of the automated magnetic tape cartridge library.

摘要： A storage and retrieval subsystem in a data processing system includes a plurality or magnetic tape cartridges, a host computer, and a library storage module storing the plurality of magnetic tape cartridges in substantially upright positions. The library storage module includes a first cylindrical array of storage cells centered about a vertical axis, a second cylindrical array concentrically arranged about the first array, and a library tape unit including a plurality of tape drives, each of the tape drives being adapted to receive one of the magnetic tape cartridges in a substantially horizontal transducing position. A robot within the library storage module is used to transfer selected ones of the magnetic tape cartridges between their substantially upright positions and the substantially horizontal transducing positions at a selected tape drive. A first controller outboard the channel communicating with the host computer is adapted to receive commands from the host computer for interfacing between the host computer and the library storage module, and a second controller inboard of the channel is adapted to receive commands from the outboard controller for interfacing between the outboard controller and the robot.
