A compact disc, is a small, round piece of a plastic called polycarbonate. It is used to record music and other sounds. When you play the disc, a laser beam inside the CD player reads a coded pattern of signals on the disc. The code is changed back into sound signals, which then go to the speakers.

Recordable CDs are finally reaching a price level that means they can be used for home recordings. CD recorders offer two recording options: rewritable and write-once.

Write-once discs can be recorded once only and cannot be edited. They can be used with all CD players. Rewritable discs can be re-recorded, although the discs can be played back only on CD-rewritable players or players that have MultiRead capability
