Floppy disks owned by George McFly.

A floppy disk, floppy, diskette, or disk is a form of disk storage comprised of a flexible magnetic storage medium that is read by a floppy disk drive.

The first floppy disks were 8-inch, were developed in the 1960s, and became commercially available in 1971. The 5¼ inch floppy disk was introduced in 1976.

By the 1980s, the limitations of the flexible floppy disks became clear. Numerous different disk sizes were introduced by multiple companies in 2, 2½, 3, 3¼, 3½ and 4 inch formats, each having a rigid case with a sliding metal cover over the head slot that allowed a computer to read the flexible magnetic storage media contained within. A variant on the 3½-inch format became the standard in 1982.

By the 21st century, floppy disks were superseded by CDs, DVDs, and internet distribution.

George McFly owned floppy disks for his MSX clone, the Nemotech MPX 125, in an alternate 1986 that was run as a police state by First and Second Citizen Brown. The most prominent of these was the Logo programming language.
