Using Disks and Disk Drives
The disk drives in your computer allow you to store data on
disk, and then retrieve and use it when you like. The Apex 100
has two 360KB diskette drives and the Apex 100\20 has one
360KB diskette drive and one 20MB hard disk.
This section explains how disks work and tells you how to do
the following:
Choose diskettes
Care for your diskettes and diskette drives
Insert and remove diskettes
Write-protect diskettes
Make backup copies of your diskettes
Use a single diskette drive
Use a hard disk drive.
How
Disks Store Data
The diskette you insert in your computer’s diskette drive is
made of flexible plastic coated with magnetic material. It is
enclosed in a square jacket that is slightly flexible. Your
computer stores data on the diskette by recording on the
magnetic surface.
Unlike a diskette, a hard disk is rigid and fixed in place. It is
sealed in a protective case to keep it free from dust and dirt. A
hard disk stores data the same way that a diskette does, but it
works faster and has a much larger storage capacity.
All disks are divided into data storage compartments by sides,
tracks, and sectors. Double-sided diskettes--like the ones you
use in your computer-store data on both sides. There are
concentric rings, called tracks, on the disk in which data is
