A virtual cartridge autoloader system is provided. A first autoloader
device has multiple cartridge holders. Each cartridge holder is
configured for electrical communication with removable data cartridges
having electronic interfaces. The first autoloader device performs
virtual loading functions on the removable data cartridges using an
electronic switch. A second autoloader device distinct from the first
autoloader device is electrically interfaced with the first autoloader
device. The second autoloader device also has multiple cartridge holders,
each of which also is configured for electrical communication with
removable data cartridges having electronic interfaces. The second
autoloader device also performs virtual loading functions on the
removable data cartridges using an electronic switch. A controller is
configured to receive media changer commands from a host computer for the
first autoloader device and for the second autoloader device. The
autoloaders may thereby be operated as a single device.
