Pressing: A stamper, which is actually a master coated with nickel layer and is a negative of the Optical Disc, is required for Optical Disc replication. At the center of the injection moulding machine is a two part mould. One half holds the stamper and the other half contains a flawless, mirror like surface. In order to produce a disc, one half of the mould closes against the other and molten polycarbonate is injected into the cavity between the stamper and the mirror surface. Only after a few seconds of pressing, a compact disc containing all the data is quickly created. The disc is then cooled to solidify the plastic, the mould then opens and the disc is removed.

Incase of a DVD, two such substrates, but half in thickness are created and then bonded together at a later stage with a transparent adhesive.

Metallization: In order for the Disc to be readable, it must be covered with a micro thin layer of aluminum which is vacuum laid. The aluminum surface acts as mirror to reflect the laser light back of the player so that information can be read. Incase of DVD Silicon Alloy is also used for metallization instead of Aluminium.

Lacquering / Bonding: To protect the CD and its information from harm—scratching, bending, or just plain dropping it on the floor—the disc is covered with a layer of varnish. The lacquer envelops the aluminum and seals it from the elements. The disc is then ready for printing.

Label Printing: The final touch comes with the printing of the label right onto the disc, by a silk screen-printing machine. The result is a clean, polished appearance with an artwork of the Disc printed on the surface. It also helps in distinguishing different Discs and provides information about the contents of the Discs.

Quality Check: The Discs are then checked for quality. The data accuracy and the playability of the Discs are tested on various testing equipments, scanners and also by playing them on computers and CD/DVD Players. The printing on the Disc is visually inspected and compared with the color proof provided by the customer.

Packing: The Discs are then packed manually either in bulk spindles or in Plastic cases, as desired by the customer. Finally the goods are packed in a carton for shipment.
