FLOPPY DISKS
8-inch, 5¼-inch, and 3½-inch floppy disks
A floppy disk is a type of disk storage composed of a disk of thin and flexible magnetic storage medium, sealed in a rectangular plastic carrier lined with fabric that removes dust particles. Floppy disks are read and written by a floppy disk drive. The first floppy disks, developed in the late 1960s, were 8 inches (200 mm) in diameter; they became commercially available in 1971 as a component of IBM products and then were sold separately beginning in 1972 by Memorex and others. These disks and associated drives were produced and improved upon by IBM and other companies such as Memorex, Shugart Associates, and Burroughs Corporation. The term “floppy disk” appeared in print as early as 1970, and although in 1973 IBM announced its first media as “Type 1 Diskette” the industry continued to use the terms “floppy disk” or “floppy”. Through its history, the floppy disks, initially as 8-inch (200 mm) media, later produced in 5¼-inch (133 mm) and 3½-inch (90 mm) sizes. While floppy disk drives still have some limited uses, especially with legacy industrial computer equipment, they have been superseded by data storage methods with much greater capacity, such as USB flash sticks, flash storage cards, portable external hard disk drives, optical discs, and storage available through computer networks.
