These days (2012) you will not find many floppy disks (although just a couple of years ago we had to order special floppy drives for a server because some software would only be installed if it booted from Drive: A a floppy).
There were 8 inch and 5 inch and 31/2 inch floppy disks which were common.
The latest (diskettes) were the smallest and were protected by a hard plastic casing. Inside a thin Mylar disk coated with a magnetic surface stored the 1.44 Mb that was the capacity of most diskettes.
Hard disks have one or more aluminium or glass disks coated with magnetic surfaces. These hold much more information and now (2012) there are units that can store 3Tb or more.
no the floppy disk rotate slower its because hard disk rotate faster then floppy disk
Hard disk has always been a hard piece of ferromagnetic metal, while the floppy disk contains only one flexible magnetic foil.
No, the floppy disk was really square and floppy. It was the original storage for the earliest PCs. Later there was a "floppy disk" that was smaller and hard. After that the round and hard CD.
The reason is that the technology of the days the floppy disk was not as advanced as of today.

Check if your floppy disk has turned into a hard drive
HDD stands for Hard Disk Drive... FDD stands for Floppy Disk Drive...

A modern hard disk will spin much faster than a floppy disk. A floppy disk will spin at around 300 RPM. A hard disk will vary depending on model and configuration. A mid range desktop hard disk will spin at around 7200RPM. Laptop hard disks usually run at slower speeds of 5400RMP. High end desktop and server hard disks can spin at speeds in excess of 10000RPM.
The head(s) in floppy drives make physical contact with the floppy disk surface, while the heads in hard disk drives fly over the hard disk surface on a cushion of air created by the platter rotation speed. All other features of the devices are similar.
A floppy typically stores 5.66 Mbytes. well i say that a typical floppy disk holds 1.44 mbytes.
It depends...when you see a hot girl... Your floppy disk might turn into a hard drive which is really big, but then it depends :)
