Format Unlimited Guide to Disc Duplication versus Replication
Duplication versus Replication for CD and DVD: What's the Difference? At Formats Unlimited we want to ensure our customers understand that the difference in Duplication and Replication is important in determining which process is best for their next project.

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 CD/DVD Duplication. Information can also added during the CD/DVD manufacturing process; this method is referred to as CD/DVD 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, or DVD-18.

Disc Duplication is similar to burning a CD/DVD on your personal computer. A CD/DVD duplicator extracts data from the master disc and writes it to a blank disc. The difference between burning multiple CD/DVD-Rs at a duplication facility and burning one on your computer desktop is that the duplication facility burns hundreds at a time on towers that are linked together. Each tower contains several CD/DVD trays so that many copies can be created simultaneously. After all the data has been written unto the blank CD/DVD-R, the information is verified with the master, and the process is complete.

Disc Replicates, on the other hand, are created during the manufacturing process. In other words, media like a CD/DVD-R does not exist before the process starts. Before the replication process gets underway, the client master is painstakingly evaluated for data corruption. Then, a glass master containing relevant data from client supplied master is created. Replication begins when a flawless glass master is assured. The glass master is used to develop a stamper. The stamper, in turn, is loaded into an Injection Molding machine that creates CD/DVD replicates. The quality of CD replication hinges upon the quality of the glass master's data. Through each successive step, quality and accuracy is consistently monitored to insure each disc is an exact replica or clone of the original. A layer of micro-thin aluminum is applied to the polycarbonate disc. It is then lacquered for additional protection and printed before packaging.

Next month we will cover the Advantages and Disadvantages of the Duplication and Replication Processes.
