Silhouette of hand holding a stack of cds. Each disc stores audio data such as music,as a series of fine depressions,representing a digitized musical signal capable of being read by a laser. To reflect the laser light,the 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 sound quality | |
