CD compact disc is a digital optical disc used to store data. Since its official introduction in 1982, CDs have peaked in sales in 2000, reaching 2,445 million copies.The disadvantage of CDs is that the sound quality produced is not as analogous as that produced by cassette tapes that can store pure sine standard sound, but is a trap or ladder shaped like a sine from the results of changing digital signals to analog signals. The advantage of CDs is the minimal noise caused by cassettes. In addition, CDs are very light and easy to carry and are durable media. CDs offer large data storage capacity and more efficient production capabilities.
