Abstract

Abstract A stacker system or an autoloader system includes a tape drive and one or more magazines which each include a plurality of tape cassettes or cartridges. A positioning system moves the magazine to a specific position to load or unload a particular cartridge or cassette from the magazine. A control system controls the operation of the tape drive and the magazines between a loaded and unloaded position. Each magazine includes a unique identification code which can be read by the stacker or autoloader to determine if the correct magazine has been inserted. In addition, each magazine includes a memory to record information about the contents of the recording media stored in the magazine or the performance of each recording media stored in the magazine.
