Floppy disks are available in various sizes and capacities.The most common are :
1. Mini floppy disks or 5.25 inch disks
2. Micro floppy disks or 3.5 inch disks
1. Mini floppy or 5.25 inch disk : The 5.25 inch disk is also known as mini floppy disk. There are two types of 5.25 inch disk :
(a) Double Sided Double Density (D.S.D.D. or 232 D) : It stores 360 K bytes of data.
(b) Double Sided High Density (D.S.H.D. or 25 H.D.) : It stores 1.2 M bytes of data.
2. Micro floppy disk or 3.5 inch disks : 3.5 inch disk is also known as Micro floppy disk. There are two types of 3.5 inch disks :
(a) Double Sided Double Density (D.S.D.D.or 252 D) : It can store 720 K.Bytes of data.
(b) Double Sided High Density (D.S.H.D.or 25 H.D. ) : It stores 1.44 M.Bytes of data.
Single Sided : When only one side of a disk is used to store information, it is called single sided.
Double Sided: When both sides of a disk are used to store information, it is called double sided.
Single Density : When a disk stores information per unit length of a track, it is known as single density disk.
Double Density : When a disk stores double information per unit length of a track compared to a single density disk, it is known as double density disk.
A Diskette will be a single density or double density depending upon recording technique.
