CARING FOR YOUR CDs & DVDs
Close this window to
Despite all of their significant advantages over other forms of recording,
compact discs (CDs) and digital video discs (DVDs) are not indestructible.
And they do require care in handling.
Many people are surprised
to learn that its the underside of the CD or DVD
the side that is NOT printed which is actually
the side which must be read (played) by your players laser beam. Dirt,
dust or scratches on this side can cause the laser beam to be thrown out
of line and result in skips or the continuous repetition of a
short segment of the music on a CD or a complete failure on the part of DVDs.
Dust can be removed each
time the CD or DVD is played by simply blowing gently across the unprinted
side of the disc. Dust can also be removed by using a clean lint-free cloth,
wiping lightly from the center of the unprinted side to the outside edge
in a straight line (not in a circle). Compressed air cans can also be used
if the air as sprayed is free of liquid propellants. More difficult
problems may actually require a moistened lint-free cloth or towel to remove
grime. No abrasive solvents or cleaners should be used that would harm
plastics or leave a residue on the discs surface.
that compact discs and DVDs be handled only by the edges. This
will minimize fingerprints on the playing surface which could cause problems.
We also recommend not placing the discs on dirty surfaces, even for a short
time, as they may pick up dust, dirt or scratches on the underside (playing
side) of the disc. Store CDs and DVDs in their original plastic containers,
with the hole in the center of the CD or DVD carefully placed on the center
mounting that is provided in the case. Don't stack discs (if not in cases).
Don't bend or twist discs. Make sure the disc is properly seated in the player
tray before closing the tray door.
Do not expose your CDs
or DVDs to direct sunlight for prolonged periods or to any other heat source
which could warp your disc. Scratches or other damage near the center hole
of the disc can be especially problematic as this is where the discs
table of contents (index) is stored. Optical players do have
a certain degree of error correction built in, but this cannot
compensate for serious damage.
If your CDs and DVDs
play properly when you first get them, any future problems are most
likely the result of use (as the discs acquire dirt or scratches)
or, perhaps, of a problem developing in your playback equipment (such as
dirt on the systems optics). Your local Radio Shack or other electronics
store has special cleaning kits available for your CD or DVD players. They
may also have special devices designed to repair faulty discs,
and, while these may help, they are often of limited value for discs which
have been seriously damaged.
and DVDs provide an amazing advance in recording technology and convenience.
With proper care, your discs will give you many, many years of listening
and viewing enjoyment.
