A floppy disk is a data storage device used for storing computer documents, photos, and other files. It consists of a thin, magnetic plastic film (where data is stored) enclosed by a nonmagnetic plastic lined with a protective fabric or cloth. It is important not to touch the magnetic film as oil and dust can damage the disk. A floppy disk can be written and overwritten on several times. It has a storage capacity of 80KB up to 1MB and higher.
The 8-inch floppy disk,also called a memory disk, can only be read but not written on. It is covered in plastic with a fabric lining, which tends to attracts dust.
5.25-inch floppy disk
The 5.25-inch floppy disk has a magnetic medium enclosing a central hub. It is covered in plastic with a fabric lining designed to prevent dust from accumulating on the magnetic medium. It has a write-enabled switch and a drive speed-regulating strobe hole. It has a storage capacity of up to 1.2MB.
3.5-inch floppy disk
The 3.5-inch floppy disk is the modern floppy disk invented in the 1980s by Sony. It has a write-enabled switch that prevents stored data from being deleted or replaced. It initially had a storage capacity of 400KB, but it can now store up to 1.44MB of files.
