Tape Cartridge Early Eject for Heat

      The following describes creating a bi-metallic, or shape
memory, spring; which creates an actuation when heated by the base of
a cartridge to eject the cartridge from the drive via means of
activating a switch or manual eject feature.

      A bi-metallic spring can be placed such that it detects
excessive heat in the base of a cartridge.  The heat can be used to
activate the spring in order to hit a switch or manual eject feature
and thereby eject the cartridge or stop it from running.

      Once the cartridge heats up to near its maximum operating
temperature, this method can become the early warning device by
either this ejection of the cartridge or by shutting down the drive
in the firmware.  A temperature sensor could also be used as a
sensing device for firmware.
