The CD/DVD Duplication Process
Published on 20 May 13

A number of people are misinformed about the process of CD/DVD duplication and replication. In as much as these two processes result in pretty much the same end product, the way each of the CDs or DVDs are produced is entirely different.
CD/DVD duplication is no different than what most computer owners do whenever they want to make a copy of a disc. It involves getting the master disc from which you want to copy from and a blank disc on which you want to copy information to. A user then inserts these discs into their respective drives and instructs the computer to copy information from the master disc to the blank disc.
Easy as that sounds, producing bulk CDs and DVDs using this process is rather challenging. This is because factors such as turnaround time, memory, speed, and processing power play a big role in this process.
With a home computer, essential devices such as the RAM and the processor aid in the disc duplication process. However, for a CD/DVD duplicator to work with the same power, it needs a good amount of RAM and some decent processors.
Typical CD/DVD duplicators that produce 5 discs require as little as 128MB of RAM for optimum performance. Bulk duplicators, on the other hand, require up to 4GB of RAM per tower. Another interesting feature of the bulk duplicator is that they can be interconnected with several other towers and instructed by a single computer.
Thus, several DVDs or CDs are inserted into each one of the disc trays on the duplicator. The user then instructs the duplicator to begin the process.
Depending on the type of media disc being used, the turnaround time also varies. If, for instance, you duplicate the DVDs in bulk, you may end up getting roughly 80-90 DVDs per hour, and for 180-200 CDs per hour from a single tower.
To make the process faster, sophisticated duplicators have hard drives of up to 500GB which store the CD and DVD masters. In this case, a lot of time will be saved in retrieving data from the master CD/DVD which is slightly slower than retrieving the same data from a hard drive.
Once complete, the discs are first verified with the master DVD/CD and then they are ejected. From here, the discs can be imprinted with covers or labels and then stored in casings.
