What's The Difference Between CD Duplication and Replication

Do you know the difference between duplication and replication of CD’s.  A lot of people don’t.  If you’re ready to get some CD’s pressed up you may need to know the difference. This blog article will explain the difference between the two.


Duplication is like burning the process of burning a CD on a computer. The information, music, data, or video is burned to the CDR. CD Duplication companies like our will bring in a stack of blank CDR’s or DVDR’s  load them into a CD Duplication tower and begin burning the info on to the CD’s. These Duplication Towers burn hundreds of CD’s at a time.  CD Duplication is usually a little more expensive per disk than replication, but may be cheaper per job depending on how many Cd’s you are trying to duplicate.


The replication process is the best and most accurate form of CD production.  Replication actually molds your data or music on to the CD. You usually start with a master CD or DVD.  A laser then copies your information on to a glass master in the form of microscopic pits.  The glass master is then electroplated to create a nickel stamper. The glass master then goes into molding machine that stamps out copies of the CD’s.

Which process is better for you? If you CD’s or DVD’s fast then you might want to go with duplication. Duplication can usually be turnaround in 24 to 48 hours, where Replication may take 10 to 15 days.  Quantity is important to. Duplication can start as low as 10 disc where replication usually starts at 300 disk or more.   As far as quality, the cd duplication process can yield a high quality product but the replication process can even yield a higher quality product.
