US nuclear force still uses floppy disks
The word disc goes back to Latin discus, which is the source of discus (mid 17th century) and also of and Late Middle English desk (discus had come to be used for a stool or table in medieval Latin). Its earliest sense in English was the seemingly flat, round form that the sun, moon, and other celestial objects present to the eye. The anatomical disc, the sort that people ‘slip’, dates from the late 19th century, as does the type that turns on a record player. In the USA the usual spelling is disk, and this is now used everywhere with reference to computers, as in floppy disk and disk drive.
