Every one has had trouble with a scratched CD. Scratched data CD can't
be read properly and in case of audio CD ,the CD skips when we play it.
The first thing to do with a CD which gives a reading error, is to
clean it; to check that the error is not being caused by a dirty
surface. You can try cleaning the CD with a soft cotton cloth by wiping
its surface . Start at the center and rub gently straight outward
towards the edge. In case of a stubborn stain,you can try using warm
water with some mild soap.Avoid sponges since they can scratch the CD.
A
CD's data is recorded on a metal layer inside it. This metal layer is
inset in a transparent plastic covering (polycarbonate) which is used
to protect the CD's metal layer and to allow printing a label on the
side not used for reading.
A CD-ROM drive uses a laser beam to
read the metal layer. This laser beam crosses the plastic layer and
reads the metal layer. If the plastic layer is scratched, the beam will
be unable to pass through it as it will get deviated, resulting in a
read error. The data to be read still lies in the CD, the trouble lies
in the layer of plastic. So how to repair this CD which holds your favorite Himesh Reshmiya's track?
As the CD's contents are preserved, a scratched CD can be recovered by polishing its plastic surface.
The
aim is to make the laser beam reach the metal surface which holds the
data, in a straight line, without any deviations and change in
intensity which may otherwise arise in a scratched CD.
Try
polishing your CD with a "toothpaste"(baking soda toothpaste).Polish
the scratches with a cotton swab. Rub gently the paste-imbued swab over
the scratches until they disappear or until you notice that you have
removed them as far as possible.Do all the cleaning gently.Do not apply
pressure.After clearing the scratches, wash the CD in water.Let the
water evaporate by itself.Do not keep the CD in sunlight.Keep it in a
cool and shady area.
DO NOT USE A GEL TOOTHPASTE.
If
the scratches still persist try using a metal polish (Brasso) in the
same way as described above. Rub Vaseline on the CD, very gently (do
not press hard).Rub from the centre to the rim. Wipe excess off using
clean, soft, lint-free cloth in a radial (inside to outside) motion. Test
disc again. If the Vaseline does the trick, burn a new copy of the CD
immediately. The Vaseline method is only a temporary solution. Go ahead..Enjoy your favourite Himesh Reshmiya's track.
