Duplication versus Replication for CD and DVD: Whats the Difference?
There are two ways to make a copy of a CD or DVD. Information can be burned on to a blank CD/DVD-R; this method is called duplication. Information can also added during the CD/DVD manufacturing process; this method is referred to as replication. Understanding the differences is important in determining which process is best for your project. A duplicated CD/DVD is not only created using a different process than a replicated CD/DVD, but the actual final product is also different. After the duplication process is complete, the final product is a CD-R or a DVD-R. Replication stampers for CDs produce CD-ROMs. (ROM means Read Only Memory). The final product in the DVD replication process is a DVD-5, DVD-9, DVD-10.
