minifloppies n.,obs.
5.25-inch floppy disks, as opposed to 3.5-inch or microfloppies and the long-obsolescent 8-inch variety (if there is ever a smaller size, they will undoubtedly be tagged `nanofloppies'). At one time, this term was a trademark of Shugart Associates for their SA-400 minifloppy drive. Nobody paid any attention. See stiffy.
