Compact discs. Abstract image showing two compact discs (CD's) in multiple exposure. Each disc stores audio data such as music,as a series of fine depressions on the disc surface,representing a digitised musical signal capable of being read by a laser. To reflect the laser light,the coded music layer is coated with a fine film of metal which follows the depressions exactly. This layer is covered by another layer of transparent plastic which prevents dust and scratches from affecting the superior sound quality | |
