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:
Use different types of diskettes and diskette drives
Care for your diskettes and diskette drives
Write-protect diskettes
Use a single diskette drive system
Insert and remove diskettes
Format diskettes
Make backup copies
Use a hard disk drive.
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 (5¼-inch diskette) or hard (3½-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
a disk can store data.
