Floppy Disk drive
A floppy disk is a data storage medium that is composed of a disk of thin, flexible ("floppy") magnetic storage medium encased in a square or rectangular plastic shell. The floppy drive reads data from, and writes data to, a small disk. The most common type of floppy drive is the 3.5" drive, followed by the 5.25" drive, among other sizes.
Today other storage devices that are more convenient and robust, such as compact disks and memory sticks, have largely replaced floppy disks. A CD can hold upwards up 600 MB, and even the smallest capacity memory stick holds several hundred times the amount of a single floppy disk.
