Disc Light Reflector
The Functioning of a CD Player
Author: Jayson Pablo
CD players are a very common item in every household nowadays. But, not every one of us is aware about how they work. If we have a closer look at the electronic market, we will find various types of players manufactured by a wide range of companies, such as Sony, Akai, and Toshiba etc. Above all, these are quite different from one another in terms of style, quality as well as design.
From the portable to the large ones, there are various types of CD players which are available in the market. In terms of cost too, the price varies from company to company. However, whatever may be the size or quality, every CD player has the basic components like a tracking device, a drive motor, and a laser and lens system. Also, all of them have the capacity to interpret data which have been stored as electric bumps.
No how do these things work? It is the drive motor which plays a major role in the functioning of the player. It makes the disc spin at a particular pace and also it gradually adjusts the speed. However, the correct pace depends upon which part the player is actually interpreting. Another important part is the tracking mechanism which helps the laser and the lens system to focus on the miniscule bumps.
The CD player works in a very interesting manner. After this the data interpreted by the laser and the lens system is stored on the surface of the CD. This data is stored in the form of elongated bumps which is only 0.5 microns big.
Also, the CD or compact disc where data is stored is a very sensitive element. It is made up of different layers of polycarbonate and aluminum. So, while trying to play a song in the CD player, firstly the laser beam tries to penetrate layer after layer. The aluminum layer is a good reflector of light, since this layer is a good reflector the changes in the reflections can be easily detected by the player.
