If playing a CD-R, the sound quality can be reduced

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, clean it with a soft,
lint free cloth or dampen a clean, soft cloth in a mild,
neutral detergent solution mixed with water. Make
