The Difference between CD Duplication and Replication


by Gwuin Ridofob


It will be easy to choose which technique you should use once you know how the CD replication technique differs from the CD duplication technique. You should base your decision on the number of CDs to be produced, how much time you can wait on the final product, and the quality of sound needed when you have your project created professionally.

When you wish to create many copies of a single CD at a time, CD replication provides a high quality manner of completing this process. This process, performed in a manufacturing facility, depends on creating a highly detailed master CD. Using this, molds are then created of the disc. Professionals use these molds to produce many CDs at a single time. This process is normally reserved for producing more than 1,000 discs.

The master CD created for this process is very special. The original sound is introduced to a recording system. This system imprints a positive version of the sound onto a master that is normally made from glass and then transferred to metal. Once these malleable surfaces are imprinted with the recording, copies are made of them with a stamping system to produce negatives. These negatives then have injection molds made of them to create positives again.

CD replication turns out an extremely good quality of music. Injection molds can make a high volume of duplicates that are also covered with an aluminum film and some lacquer for protection. These also go through a hardening process under an UV light before they are ready to use.

The CD duplication process is less complicated, and produces a single copy of a disc at a time. Normally, it is used for creating fewer than 1,000 duplicates. In this process, a computerized disc drive is used to transfer the sounds off an original CD. This recording is then transferred, or "burned", onto another CD to create a perfect replica.

You choose your CDs from three main types of them for this process. Stereo systems and computers that are older are compatible the CD-Rs. The newer DVD players, car and home stereos, and computers will play the CD+Rs and CD-Rs. Select which one you need by the targeted audience. Now, there is also the rewritable version of blank CDs called CD-RWs. These can be recorded, erased, and re-recorded if necessary similar to the old VHS tapes.

I don't believe that CD duplication returns quite the same caliber of disc as the replication process. But, from what I've read, it is negligible.

Which of these processes you choose will make a slight difference in your final product. While CD replication does produce a slightly better product, it generally takes more time and is cost prohibitive for runs under 300 pieces. CD replication produces the standard shinny discs and duplication is on the greener discs. Duplication is normally faster. Keep these facts in mind when choosing which method you want to use in creating your CDs. Remember to plan ahead for either process.
