Floppy disks (or diskettes) are magnetic disk data storage formats, usually composed of a thin, flexible disk sealed in a rectangular plastic carrier. In many cases the carrier is rigid, and the word floppy refers to the disc inside. Capacities can range from just a few KB (such as the Olivetti minidisc, with an initial capacity of 3KB) to 750KB for the largest capacity Zip disk.
The sizes below relate to the form factor of the disk drive, and the disk itself may not be the exactly the size listed.
For a version of this page that can fit on a floppy disk, visit the The Floppy Disk Museum on a Floppy page.
Optical, magnetic-optical, hard disks and others can be found the on the main Disks / Discs for Data page.
