If you have spent any time at all working with a computer, then chances are good that you have used a floppy disk at some point. The floppy disk drive (FDD) was the primary means of adding data to a computer until the CD-ROM drive became popular. In fact, FDDs have been a key component of most personal computers for more than 20 years.

Basically, a floppy disk drive reads and writes data to a small, circular piece of metal-coated plastic similar to audio cassette tape. In this article, you will learn more about what is inside a floppy disk drive and how it works. You will also find out some cool facts about FDDs.

The floppy disk drive (FDD) was invented at IBM by Alan Shugart in 1967. The first floppy drives used an 8-inch disk (later called a “diskette” as it got smaller), which evolved into the 5.25-inch disk that was used on the first IBM Personal Computer in August 1981. The 5.25-inch disk held 360 kilobytes compared to the 1.44 megabyte capacity of today’s 3.5-inch diskette.

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.

Parts of a Floppy Disk Drive:

Disk: Also called diskette. The common size is 3.5 inches.

Drive: The electromechanical device that reads and writes floppy disks.

Tracks: Concentric ring of data on a side of a disk.

Sectors: A subset of a track, similar to wedge or a slice of pie.
