Description
Compact disc (CD) used for storing data. CDs consist of a sheet of plastic and metal which has a surface covered in microscopic pits. A laser scans the surface as the disc rotates and detects the pits, which it converts into a stream of data. CDs can be used to store music, text and digital images.
