SEM of compact disc musical layer
Bildnummer 11896942
| Scanning electron micrograph of the surface of a compact disc cracked to show the musical layer below (here the plain grooves between tracks). The disc is made of plastic,which is pressed with a series of fine depressions 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,which is visible here. The music is sandwiched between two layers of plastic,which prevents dust & scratches from affecting the sound.
