But the reality is that the discs are still hard to keep in the long term, optical records record signals by carving holes in the surface of the disc, and then coating it with an aluminum film to reflect the signal. The cd-rw is achieved by laser burning the chemical material on the cd-rw to change the reflection, among them, there are small pit and no pit or burn and unburned place to reflect light differently. The optical disc machine reads the data by emitting a laser beam that reflects light from the disc, Therefore, it very Read more
