floppy disk a flexible removable magnetic disk that stores information and can be used to store data for use in a microprocessor floppy disk[¦fläp·ē ′disk] (computer science) A flexible plastic disk coated with magnetic oxide and used for data entry to a computer; a slot in its protective envelope or housing, which remains stationary while the disk rotates, exposes the track positions for the magnetic read/write head of the drive unit. Also known as diskette. floppy disk (hardware, storage)(Or "floppy", "diskette") A small,portable plastic disk coated in a magnetisable substance usedfor storing computer data, readable by a computer with afloppy disk drive. The physical size of disks has shrunk fromthe early 8 inch, to 5 1/4 inch ("minifloppy") to 3 1/2 inch("microfloppy") while the data capacity has risen.
These disks are known as "floppy" disks (or diskettes) becausethe disk is flexible and the read/write head is in physicalcontact with the surface of the disk in contrast to "hard disks" (or winchesters) which are rigid and rely on a smallfixed gap between the disk surface and the heads. Floppiesmay be either single-sided or double-sided.
3.5 inch floppies are less floppy than the larger disksbecause they come in a stiff plastic "envelope" or case, hencethe alternative names "stiffy" or "crunchy" sometimes used todistinguish them from the floppier kind.
The following formats are used on IBM PCs and elsewhere:

Double denisty and high density are usually abbreviated DD andHD. HD 3.5 inch disks have a second hole in the envelope andan overlapping "HD" logo.floppy diskAn earlier, reusable magnetic storage medium and drive introduced by IBM in 1971. Officially a "diskette," it was nicknamed "floppy" because the first varieties were housed in bendable jackets. In the late 1970s, the floppy was the first personal computer storage medium. Although computers with hard disks emerged in the 1980s, they had at least one floppy drive for distributing applications, backup and data transfer between machines. By the mid-1990s, the floppy gave way to the CD-ROM for software distribution, while local networks and the Internet became popular for backup and data exchange.
Like Magnetic Tape
The floppy's recording surface was a circular platter of magnetically coated plastic similar to magnetic tape, except that both sides were recordable. The drive grabbed and spun the platter inside its jacket, while the read/write head contacted the surface through an opening. At 300 RPM, floppies rotated considerably slower than a hard disk, and they came to a complete stop when there was no read/write activity.
Format Before Writing
Every new floppy had to be "formatted," which divided the disk into sectors (see format program). However, by looking at the external jacket, one could not always discern the recording format. See magnetic disk.
