minifloppy

from The Free On-line Dictionary of Computing (8 July 2008)

minifloppy

   <storage> 5.25-inch {vanilla} floppy disks, as opposed to
   3.5-inch or {microfloppies} and the now-obsolescent 8-inch
   variety.

   At one time, this term was a trademark of {Shugart Associates}
   for their SA-400 minifloppy drive.  Nobody paid any attention.

   See {stiffy}.
