A CD is almost entirely made of polycarbonate plastic. The top of the plastic has a spiral track molded into it. A small layer of aluminum or occasionally gold is applied to the disc. It gives the surface of a CD its reflecting quality. The glossy metal coating reflects the laser used to read or write the device. The CD is spin-coated with lacquer to shield the metal. A label may be offset-printed or screen-printed onto the lacquer. The data is encoded by forming pits in the polycarbonate's spiral track.
