The creation of the compact disc, better known as the CD, can be traced back to the late 1960s. A Dutch scientist named Klass Compaan of Philips Research conceived the idea for the CD. He teamed with another scientist, Piet Kramer, who together introduced the first color videodisc prototype in 1972. Sony teamed up with Philips on the creation of the compact disc, and together they were able to develop a standard, universal compact disc to hold audio information. The two companies officially announced the Digital-Audio disc in 1980. In 1982, the compact disc was introduced to the public in Europe and Japan. Later, in 1983, it was introduced in the United States (Future).

Compact Discs are flat and circular, with a diameter of 120 millimeters. The actual disc itself is made of hard plastic covered with aluminum or some other reflective metal. Information is stored on the compact disc in numeric form, also called digital form. The primary use for the compact disc is to store and play back music. However, they can also be used to store pictures, files of text, sounds, programs, video games, high quality images, or motion pictures. Many features of the compact disc are standardized, such as its size, minutes of sound, and data format. This allows a compact disc to be played on any compact disc player (Pohlmann, 901).

Compact discs are read by a laser, or in other words, they are optically read (Feldman, 160). Therefore, there is no friction needed to play back the information on a CD, as opposed to th...
