How does a Floppy Disk work?


A Floppy Disk is a plastic disk coated with magnetic material. Data is stored in the disc in concentric circles called tracks. Each track consists of tiny magnetic spots whose orientation desides whether a ‘1’ or a ‘0’ is stored in that spot. This disc is enclosed in a hard rectangular jacket. There is flat circular metallic connector at center of the disc and a window on the hard jacket-through which the floppy disk can be viewed. This window is usually covered by a metallic covering that is sliding type and fixed on the hard jacket. When floppy is inserted in the floppy disk drive, a spindle goes into the circular connector and make the floppy rotate. The metallic covering over the window is slided and head is positioned over the disc through this window and read/write operations are performed. Commonly available floppy disks are of high density type and they can store upto 1.44 MB data.
