What is CD replication?

CD replication is the physical production process involving actually pressing the discs during manufacture from a glass master. Replicated discs are referred to as CD ROM discs, with the 'ROM' standing for 'Read-Only Memory' (as opposed to the CD-R where the 'R' stands for 'Recordable').

The glass master is made of a solid thick disc of glass that has been coated by a chemical, which is burned off with a laser. The glass master is a 'negative' of the CD and it is then coated with a molten nickel compound and turned into a  'stamper'. The stamper punches tiny pits in the discs that use molten aluminium as the reflective surface and two polycarbonate layers sandwich the aluminium layer to help protect it.

CD replication is a very quick and cost-effective production method for larger quantities of discs (1000 or more). However due to the high setup costs this type of production is not suitable for smaller production runs.

Replicated CDs are then printed using a five colour silk screen or offset lithographic process, resulting in a very high quality disc.

The other main type of CD or DVD production is referred to as CD duplication and is suitable for smaller production runs with quicker turnaround times. CD and DVD duplication involves burning blank CD and DVD media with a laser to add the file contents onto the discs.
