CD Player

From Wikipedia, a free encyclopedia written in simple English for easy reading.

A CD player is an electronic device used to read sounds and music from compact discs.

When a Compact Disc (called a CD) is played with a CD player, a laser (a light beam) strikes the surface of the disc as it revolves (spins around). The laser moves back and forth at one side of the disc, but because the disc is spinning, the laser can read the whole disc. As the CD player is reading the disc like this, the electronics turn what the laser reads into sound.

CD players can be attached to large home stereos, small enough to be portable, or part of a car for listening to CDs while driving.
