Floppy disk consists of a thin plastic disk coated with magnetic material. It is enclosed in a plastic jacket. Floppy disks store much less data than a CD-ROM disk or USB flash drive. A normal 3½ inch disk can store 1.44 MB of data. This is usually enough for simple text documents.
How it stores data
The head of the floppy disk drive easily manipulates the magnetic coating on the disk to store information. Information is recorded on circular tracks and triangular sections. A special head in the drive erases the area to be written before recording occurs to ensure recorded information is not contaminated from previous information recorded nearby.
