Main article: CD manufacturing

In optical disc manufacturing, storage replication is the process of producing discs via methods that do not involve burning blank CD or DVD discs; the latter is called "duplication".

The replication of optical discs involves:

1. the creation of a glass master from a client original master
2. the creation of a nickel stamper from that glass master
3. the injection molding of clear optical-grade polycarbonate substrates (clear discs) from that stamper
4. the metallizing and lacquering of those substrates to produce compact discs and DVDs.
