Caption: Scanning electron micrograph (edge on) of a compact disc cracked to show the musical layer (foreground) below the outer plastic covering (background). The disc is made of plastic, which is pressed with a series of fine depressions (seen), representing a digitised 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 (unseen) which follows the depressions exactly. This layer is covered by another layer of transparent plastic. The music is sealed between two layers of plastic, which prevents dust & scratches from affecting the sound. Mag:X3000 at 10x8 inch, x430 at 35 mm size.
