Compact disc player

From ArticleWorld

A compact disc (CD) player is an electronic device which uses a laser to read digitally-recorded data from a compact disc. The data is then converted into electrical signals. Depending upon the capacity and make, CD players can hold up to five CDs at the same time.

Categories of CD players

The term CD player may refer to one of the three classes described below: 1) Digital stereo systems, which can retrieve digitally-recorded sound data on CDs. These refer to systems used in homes. 2) Portable players that can be easily carried around during traveling. 3) Units capable of playing either MP3 or other compressed audio formats; equipped with amplifiers and powerful speakers.

Precautions during use

Although CD players are known to be very convenient, their use requires a few precautions. Vibrations can cause them to fail, or skip some audio data while playing. Newer models of CD players have overcome this problem to a great extent. Apart from this, care should be taken to ensure that there is no scratch or dirt on the CDs to prevent them from being misread.

CD players and their widespread use

CD players are found in stereo systems used at home or at functions, car audio players, personal computers and as portable audio players that can be used during trips and under harsh conditions of shock and vibration.

CD players, being digital devices controlled by semiconductor lasers, have several features which conventional cassette tape players lack. Tracks on an audio CD can be instantly changed and repeated a desired number of times. Most CD players come with user-friendly interfaces.

In recent times, DVD and MP3 players have been becoming popular because of their ability to store videos of high resolution as well as superior quality sound.
