The Floppy disk, floppy, disk, or diskette, is a magnetic storage format.

8-inch floppy

In 1967, IBM released the 8-inch floppy disk for use with their System/370 mainframe computers.

5¼-inch minifloppy

Shugart Associates released the 5¼-inch minifloppy in September 1976.

3½-inch floppy

Sony released the 3½-inch floppy in 1981. This format had a hard plastic case that protected the magnetic disk.

5¼-inch FileWare

On January 19, 1983, Apple released the proprietary 5¼-inch FileWare, code-named "Twiggy", for use in their Lisa computer. The FileWare format is similar to the standard 5¼-inch minifloppy, however, it has additional write windows on the top of the disk, and the label runs down the side.

2⅘-inch Quick Disk

Mitsumi released the 2⅘-inch quick disk in 1985. The most successful use of this format was the Family Computer Disk System, released in Japan in 1986.
