CDs are found practically everywhere
that technology is involved these days. They are used
to store information of all sorts, ranging from music
and movies to software and data.
The principle function of a
CD is to store large amounts of data in a medium that
is durable, easy to use and can be stored and transported
without hassle. The main downfall of a CD is that it
can be ruined by bad scratching of the read surface,
although as long as the metal surface itself has not
been damaged then recovering the disc is possible.
