In fact, a CD is almost pure polycarbonate plastic. There is a spiral track molded into the top of the plastic. The surface of a CD is reflective because the disc is coated with a thin layer of aluminum or sometimes gold. The shiny metal layer reflects the laser that is used to read or write to the device.
