disk-shaped sheet of plastic that
magnetically stores data on its
coated surfaces. Floppies are
contained within stiff plastic
"envelopes" to protect them from
dust, fingerprints, and abrasion.

to read and write data on
concentric disk tracks.
floppy drive A device that stores
data on a floppy diskette.
