The Compact Disk
The compact disk (CD) was introduced by Philips and Sony in 1980 to replace LP records. It is a small plastic disk with a reflecting
metal coating, usually aluminum. Myriad's of tiny indentations are burned into this coating. These indentations contain the music in
millions of bits. The CD is organized in tracks. Each track is assigned a number.
The big advantage of the CD is its high-quality music reproduction and total absence of back ground noise as well as a great
dynamic. During operation, the software in the drive can correct errors caused by such things as finger marks on the disk. All in all,
the CD is an excellent music storage media.
