6 ημέρες πριν · compact disc (CD), a molded plastic disc containing digital data that is scanned by a laser beam for the reproduction of recorded sound and other information. Since its commercial introduction in 1982, the audio CD has almost completely replaced the phonograph disc (or record) for high-fidelity recorded music.
The story of the CD started way back in 1957 with experiments involving the rudimentary video disc by the Italian Antonio Rubbiani, that stimulated an entire generation of scientists to think along the lines of digital technology.
In 1877 "Mary Had a Little Lamb" was recorded and played on Thomas Edison's first experimental talking machine called a phonograph. About one hundred years (1982) after Edison's introduction of the phonograph, two companies, Sony and Philips, marketed the first digital audio 5-inch compact disc (CD).
In 1976 Phillips and Sony developed the compact disc (CD), an optical disc used to store and playback digital data. It was originally developed to store and playback sound recordings exclusively. CDs can hold up to 700 megabytes. This equates to up to 80 minutes of uncompressed audio. By 2007 200 billion CDs were sold worldwide.
