Compact discs (CD) are laser-read data storage devices used for audio, video or textual material storage solutions. Used for years simply for audio recordings, recently CD have become a widely used integration for computer systems, using their massive amounts of data storage for large programs, upgrades, and other reference materials. A CD stores information digitally, therefore improving their rate of playback and longevity. During play, a low-powered laser beam reads the digital information through the reflective rear surface of the disk. CD should be kept dust-free as much as possible, as particle formation on their surface corrupts the laser reading.
