The Floppy disk, floppy, disk, or diskette, is a magnetic storage format.
Shugart Associates released the 5¼-inch minifloppy in September 1976.
Sony released the 3½-inch floppy in 1981. This format had a hard plastic case that protected the magnetic disk.
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.
