Floppy Disk System
Fixed Disk drive is equipped with a permanent disk or disk pack. Exchangeable disk drives provide
for easy interface of disk or packs. Disk made from synthetic plastic like material are flexible and
therefore called floppy disk or floppy diskettes. These are cheaper and more rugged and are
designed so that they can be portable. Each floppy is packed inside a protective envelope which
gives it rigidity and cleans as it rotates.
Sizes of the disks
Disks come in varying sizes – rigid disks are made of four standard diameters. Large mainframes
and mini computers normally use 14 inches (365 mm) rigid disks in packs of upto 12, small
computers use 8”, 5.25” and 3.5” diameter fixed disks also known as Winchesters Disks.
The floppy disk gets its name from the facts that it is made of plastic material. This plastic base is
coated with iron-oxide recording substance. Data is recorded as tiny invisible magnetic stops on this
coating. This is covered with plastic jacket for safety purposes. The functioning of a floppy is similar
to a record player. If you take out actual media out of plastic jacket, you will find it similar to audio
record with number of tracks on it. You can get data randomly. Each floppy has one index. You can
see a hole in the floppy. This is the index where address of data is stored. A floppy is divided into
tracks and sectors, each sector can hold 512 bytes of information.
Floppies are available in three sizes – 8”, 5.25” and 3.5”
