Using a CD-ROM Drive
Some PC models have a preinstalled CD-ROM drive. CD-ROM (compact disc
read-only memory) technology offers quick access to enormous amounts of
information. A compact disc can store more than 650 MB of data, such as the large
files needed for audio, still and full-motion video, and still and animated graphics.
A CD-ROM drive can play back or read from a CD, but it cannot write information
to it. CD-ROM drives use industry-standard, 12 cm (4.75-inch) CDs.
Follow these guidelines when using a CD-ROM drive:
Do not place the drive where there is:
– High temperature
– High humidity
– Excessive dust
– Excessive vibration or sudden shock
– An inclined surface
– Direct sunlight
Do not insert any object other than a CD into the drive.
Before moving the computer, remove the CD from the drive.

Handling a CD
When handling a CD, follow these guidelines:
Hold the CD by its edges. Do not touch the surface.
To remove dust or fingerprints, wipe the CD from the center to the outside.
Wiping the CD in a circular direction might cause loss of data.
Do not write or stick paper on the CD.
Do not scratch or mark the CD.
