Optical Drive And Its Types (CD, DVD, BRD):

An optical drive uses lasers to read data on the optical media. It is made of polycarbonate plastic. The concept of CD was co-developed by Philips and Sony in 1982. The first CD was created on 17 August 1982 at the workshop of Philips in Germany.

There are three types of optical drives:

1.    Compact disc (CD)
