The Difference between DVD Replication and Duplication

Most people don’t realize there are two different ways to mass produce copies of CDs and DVDs: duplication and replication.

At home, you “burn” information such as music or movies onto blank CDs or DVDs. This is called duplication. Replication is when the information is added during the manufacturing process. Here are the important differences between the two.


Duplication is a simple process that only takes two to three days, even for large orders of 5,000 units or more. The process starts by extracting the necessary data from a master disc, much like when burning a CD at home, and writing it on a blank disc.

The difference between doing it at home and at a facility is that the facility mass produces thousands at a time. The final product, including digital full color printing, is a CD-R or a DVD-R.


Replication is not as simple a process. This is because it includes the production of the master disc, which is made from glass. The data provided by clients is thoroughly inspected to ensure no encryptions are encountered. Then a glass master copy is created and used to develop a stamper. The stamper is placed in a injection molding machine that will replicate the CDs and DVDs.

To complete each disc, a thin layer of aluminum is applied, lacquered, and finally printed before packaging. Despite initially being a longer process, it can create more copies of discs for less money than duplication.
