Answers:    A Compact Disc is made from a 1.2 mm thick disc of almost pure polycarbonate plastic and weigh approximately 16 grams. A thin level of aluminium or, more rarely, gold ingots is applied to the surface to make it reflective, and is protected by a picture of lacquer. The lacquer is normally spin coated directly over the reflective layer. On top of that surface, the sticky label print is applied. Common printing methods for CDs are screen-printing and offset printing.

The process of creating a finished DVD product begin with the construction of the disc, which consists of four biggest layers. The first shroud is made up of a thick polycarbonate plastic, resembling that of a compact disc. Above that is a strong layer of thick, reflective material, followed by a transparent seam of thin motion picture. Finally, a protective layer of plastic is added to the foundation.
Most DVDs are of matching dimensions as compact discs (CDs) but store more than 6 times as much data.
