Floppy Disk :-

• A floppy disk is a flat, circular piece of flexible plastic coated with magnetic oxide. It is encased in a square plastic or vinyl jacket cover.
• The jacket gives handling protection to disk surface.
• Moreover, it has a special liner that provides a wiping action to remove dust particles, which are harmful to disk surface and read/write head.
• Floppy disks are so called because they are made of flexible plastic plates that can bend.
• They are also known as floppies or diskettes.
• IBM introduced them in 1972. Until recently, they were one of the most popular and inexpensive portable secondary storage medium used in small computer systems.
• Two popularly used sizes of floppy disks were 3½-inch and 5¼ -inch. However, portable hard disk, optical disk, and pen drive have now replaced them because these storage devices outperformed floppy disk in storage capacity, access speed, and reliability.
• These are small removable disks that are plastic coated with magnetic recording material. Floppy disks are typically 3.5 in size (diameter) and can hold 1.44 MB of data. This portable storage device is a rewritable media and can be reused a numberof times.
• Floppy disks are commonly used to move files between different computers. The main disadvantage of floppy disks is that they can be damaged easily and, therefore, are not very reliable. The following figure shows an example of the floppy disk.
