DISKETTE

			A synonym for the term "floppy disk". Each diskette
   ███████████████	drive has a default capacity (see below), but can
   ██████████████▌	usually read other diskettes of the same size and
   ██████▌ ▐██████	lesser capacity. A drive can occasionally write to a
   ███████▀███████	diskette of lesser capacity, but only rarely can it
   ███████░███████	be used with the FORMAT or BACKUP command to create
   ███████▄███████	a diskette that can reliably be read by a lesser
			capacity drive.

    Physical size     Capacity(Kb)	Description	Sectors/Track Tracks
    -------------     --------		-----------		--	--
	5 ¼"		160		single-sided (DOS 1.1)	 8	40
	5 ¼"		180		ancient single-sided	 9	40
	5 ¼"		320		oldest double-sided 	 8	40
	5 ¼"		360		old double-sided 	 9	40
	5 ¼"		1200		old high-capacity 	15	80

	3 ½"		720		recent double-sided 	 9	80
	3 ½"		1440		recent high-capacity 	18	80

Kb= 1,000 bytes = 1,000 characters. In all cases, one sector of a disk contains
512 characters.
