Compact discs. Photograph of several audio compact discs (CD). The CD stores music as 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, normally aluminium, which follows the depressions exactly. The reflective surface is covered by a thick layer of transparent plastic which prevents dust scratches from affecting the sound quality. A standard audio CD can store about 80 minutes of music.
This photographic print is digitally printed on archival quality paper with vivid color and exceptional detail, suitable for museum or gallery display.
