WHAT'S IN THE NAME? CD BURNING

CD-Rs and CD-RWs are made up of a poly carbonate substrate, a thin metal coating, and a protective outer layer.In a CD-R a layer of organic polymer dye between the poly carbonate and the metal layers serves a a recording medium. The laser creates marks(burns) in the dye layer that mimic the reflective properties of the pits and lands(lower and higher areas) of the cd.Due to this CD writing is also known as CD BURNING
