Replication (optical media)

From Wikipedia, the free encyclopedia

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