Difference between Hard Disk and Floppy Disk :
| HARD DISK | FLOPPY DISK |
|---|---|
| It uses 2-4 metallic disk called platter. | It contains single plastic disk. |
| Data storing surface is coated by magnetic oxide. | Data storing surface is exposed. |

When was the first floppy disk introduced?

Why is it called a floppy disk?
The floppy disk drive (FDD) was invented at IBM by Alan Shugart in 1967. The 5.25-inch disks were dubbed “floppy” because the diskette packaging was a very flexible plastic envelope, unlike the rigid case used to hold today’s 3.5-inch diskettes.
What are the characteristics of floppy disk?
The most common size of floppy disk is 3½ inches. It has a jacket of hard plastic with a metal shutter protecting the read-write slot. Floppy disks typically hold 1.44 megabytes. A former type of 5¼ inch diameter, which was held in a flexible paper envelope, is now obsolete.

What was the capacity of a floppy disk?
The first 8-inch floppy disk had a storage capacity of about 80 kilobytes. By 1986, IBM introduced the 3-1/2 inch floppy disk with 1.44 megabytes of storage space. This may seem like very little now, but at the time it was hard to imagine needing more space than that.
