When you handle CDs and DVDs, pay attention to the following guidelines:
•
Always pick up the disk by its edges.
• Avoid scratching or soiling either side of the disk.
• Do not write with the hard ball-point pen or apply labels on either side of
the disk.
• Keep the disk away from direct sunlight or high temperatures.
• Clean fingerprints or dust from the disk by wiping it with a soft cloth.
The above points also apply to other optical storage media.
