The FIND CARTRIDGE command locates a named cartridge in any media robot
    which includes a vision system.  If the named cartridge resides in the
    media robot, MRU software returns its location.

    NOTE:  This command uses the name on the external label affixed to the
    cartridge, it DOES NOT use the name of the recorded label on the medium.
