A DVD and CD player is a device that is used to play back DVDs and CDs. They are available in a variety of forms, including portable and desktop players, as well as inbuilt players that are found in many televisions and computers.

DVD and CD players use a laser to read the data on a disc. The laser is focused on a specific point on the disc, and the player then spins the disc so that the laser can read the entire surface. The player uses this information to create an image that is displayed on the screen.
