Using Disks and Disk Drives

The disk drives in your computer allow you to store data on disk,
and then retrieve and use your stored data. This section explains
how disks work and tells you how to:

How Disks Store Data

Diskettes. are made of flexible plastic coated with magnetic
material. This plastic is enclosed in a square jacket that is either
slightly flexible (S+inch diskette) or hard (3l/z-inch diskette).
Unlike a diskette, a hard disk is rigid and fixed in place. It is
sealed in a protective case to keep it free of dust and dirt. A hard
disk stores data the same way that a diskette does, but it works
much faster and has a much larger storage capacity.
All disks are divided into data storage compartments by sides,
tracks, and sectors. Double-sided diskettes store data on both
sides. On each side are concentric rings, called tracks, on which
the computer stores your data.
