Electronics

  • (written as CD)
    Abbreviation of compact disc. A digital optical storage medium, usually 12 centimeters in diameter, whose contained information is encoded in microscopic pits on its metallic surface, which is protected by a plastic layer. Since there is no contact between the pickup and the recorded surface, wear is minimized, and the protective layer helps avoid reading errors due to dust or minor marks on the surface of the disc. To recover the recorded content, a laser is focused on the metallic surface of the disc, and the reflected light is modulated by the code on said disc. Compact discs can be used to store any type of digitally encoded information, and are used especially for music, computer multimedia content, or movies. A music CD, for instance, can usually hold up to 74 minutes of recorded sound, a CD-ROM can store up to around 680 megabytes, and the capacity of a DVD is up to 17 GB.
