A floppy disk, also called a floppy, diskette, or just disk, is a type of disk storage composed of a disk of thin and flexible magnetic storage medium, sealed in a rectangular plastic enclosure lined with fabric that removes dust particles. Floppy disks are read and written by a floppy disk drive (FDD). Floppy disks were a ubiquitous form of data storage and exchange from the mid-1970s into the mid-2000s. By the late 2000s, computers were rarely manufactured with installed floppy disk drives.In the early 1980s, a number of manufacturers introduced smaller floppy drives and media in various formats. A consortium of 21 companies eventually settled on a 3½-inch floppy disk (actually 90 mm wide), a.k.a. Micro diskette, Micro disk, or Micro floppy. Single-sided drives shipped in 1983, and double sided in 1984. What became the most common format, the double-sided, high-density (HD) 1.44 MB disk drive, shipped in 1986. All 3½-inch disks have a rectangular hole in one corner which, if obstructed, write-enabled the disk. A sliding detented piece can be moved to block or reveal the part of the rectangular hole that is sensed by the drive. The HD 1.44 MB disks have a second, unobstructed hole in the opposite corner which identifies them as being of that capacity.
