1/4-Inch Dry Cleaning Cartridge

      Dislosed is a 1/4-inch Dry Cleaning Cartridge which will allow
for preventive head cleaning without the use of chemicals or
solvents.

      Currently, 1/4-inch tape drives use a wet cleaning cartridge
which requires a chemical solvent.  Chemical solvents, in general,
are difficult to ship.

      The current cleaning method also requires human intervention to
change pads and regulate the cleaning duration.  This is not as
reliable as drive controlled cleaning.  The current cleaning method
is unsuitable for use in tape automation or library products.

      The solution is a Dry Cleaning Cartridge (DCC) for the 1/4-inch
tape drive.  The recognition of the 1/4-inch DCC occurs in a very
different manner than other cleaning cartridges.  Typically, dry
cleaning cartridges are recognized through a file protect indication
and no-cartridge present.

      The 1/4-inch DCC will utilize the drive's beginning of tape and
end of tape sensors along with a shutter system in the DCC to
correctly detect the cleaning cartridge.  The specifics of the DCC
detection scheme are as follows:
  1.  Upon insertion of the DCC, both drive
End-of-Tape/Bottom-of-Tape
       (EOT/BOT) sensors are open.  This state signifies either a
       tape-off-spool cartridge or a DCC.
  2.  The drive will then move the capstan forward for a short
       distance.  The movement of the capstan causes the filament to
