Commercial CDs
• Materials/Process:– Injection molded PC imprinted with bumps by
master stamp.– Aluminum is sputtered over bumps– Protective acrylic layers sprayed over top– Label painted on top of acrylic.

Commercial CDs
• Mastering: process of creating a stamper to be used in the injection molding stage of manufacturing compact discs. – A laser etches the digital pattern onto a highly
polished glass disc coated with photoresist – "glass master" is then cured (developed) with
ultraviolet light and rinsed off – A metal mold is electroformed– The mold is removed and electroplated with nickel to
be used as the stamper.
