ABSTRACT:
A forced recording medium cartridge unloading system for use with a library apparatus which is operatively connected to a plurality of host computers. Interposed between the host computers and the library apparatus is a library controller that supervises and controls the library apparatus. The library controller issues a forced recording medium cartridge unloading command in response to a key input or to a request from any one of the host computers. An accessor of the library apparatus upon receipt of the forced unloading command from the library controller in turn issues a forced recording medium cartridge unloading command to a recording medium drive unit that writes and reads data to and from the recording medium cartridge loaded therein. This causes the recording medium drive unit forcibly to unload the recording medium cartridge left loaded inadvertently therein.
