Care of CDs
If playing a CD-R, the sound quality can be reduced due
to CD-R or CD-RW quality, the method of recording, the
quality of the music that has been recorded, and the way
the CD-R or CD-RW has been handled. Handle them
carefully. Store CD-R(s) or CD-RW(s) in their original
cases or other protective cases and away from direct
sunlight and dust. The CD or DVD player scans the
bottom surface of the disc. If the surface of a CD is
damaged, such as cracked, broken, or scratched, the CD
does not play properly or not at all. Do not touch the
bottom side of a CD while handling it; this could damage
the surface. Pick up CDs by grasping the outer edges or
the edge of the hole and the outer edge.
If the surface of a CD is soiled, take a soft, lint free cloth
or dampen a clean, soft cloth in a mild, neutral detergent
solution mixed with water, and clean it. Make sure the
wiping process starts from the center to the edge.
