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.
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.
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.
