Duplication vs. Replication: What’s the Difference?

Understanding the many differences between CD or DVD replication and duplication can help you decide which process is best for your project. Duplicated CDs and DVDs are made with a different procedure than replicated CDs and DVDs. The final results are different, as well. Read on to learn more about the differences and which process best suits your project.


CD/DVD duplication is basically recording (or burning) data onto a blank CD-R (recordable) disc. For large-scale projects in which several discs need to be duplicated at once, a multi-disc duplicator is recommended. Multi-disc duplicators are commonly used to optimize burn speeds and media to ensure quality results. Thermal or inkjet printers for labeling the discs are ideal for a professional finishing touch. Disc duplication professionals usually have these kinds of equipment on hand. Disc duplication is less time consuming than replication, making it more cost effective, especially for lower quantities of copies. They are also completed in less time, which makes duplication a popular choice for projects with tight deadlines.


CD and DVD replication can be a painstaking process. Replication is a production process that requires pressing discs during the manufacturing process by a glass master. A glass master is a “stamper” that evaluates data for corruption and then punches data pits into a disc during the replication process. Replicated discs result in CD-ROM (read-only memory) discs. During this process, the glass master monitors the replication progress to ensure that each replicated disc is an exact replica of the original. Finally, a thin layer of protective aluminum is applied and lacquered to the disc. Replication results in a more polished, professional look with premium playback quality. They, too, can be cost effective if ordered in a bulk amount.
