Compact Disc Players
Since their introduction in 1983, compact discs
have become the best recording medium for music. Unlike record
albums and tapes, compact discs cannot be damaged with nomal use.
A standard-sized compact disc is less than five inches in diameter and is capable of storing up to 75 minutes if digitally encoded music. Each disc contains billions of tiny pits that represent musical signals with numeric codes. A beam of laser light reads these pits and converts the codes into musical signals.
Compact disc players have a wide variety of features. The following list will help you choose exactly what you would like in a compact disc player.
