Compact disc drive. View of a compact disc (CD) drive of a personal computer (PC). CDs are a very powerful storage medium for information. Information is stored in digital form as a pattern of pits on the aluminium-coated plastic disc. A laser then scans the compact disc. A single CD-ROM disc may store 600 megabytes of data or more,equivalent to some 300,000 pages of text. As they can also store images and sound,CD-ROM discs are used to run multimedia computer programmes. Also seen is a floppy disc drive (at lower right) and the PC in the background | |
