Question

how does a optical drive read and write data​

Answer 1

An optical disk drive uses a laser to read and write data. ... An optical drive that can work with multiple types of discs will therefore contain multiple lasers. The mechanism to read and write data consists of a laser, a lens to guide the laser beam, and photodiodes to detect the light reflection from the disc.
