Simple Facts About CD Duplication and Replication

By Frank Smalls


Once you understand the differences between CD replication and CD duplication, you will immediately know which process you need. When you are having your project professionally created, your final decision will depend on three concepts: how many new CDs you need to make, how long you are willing to wait for them, and what level of sound quality you require.

When you need to make a lot of duplicate of one CD in one production run, CD replication is ideal for turning out high quality copies. This procedure should be performed with the help of professional-quality devices, to turn out a top-quality CD master. With this method, molds are made of original disc. The professionals, to make numerous CDs in one run, then use these molds. This method is typically only used for runs of 1,000 discs or more.

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.

CD duplication is not as complex, and can make just one copy at one time, if so desired. This process is used for making fewer than 1,000 copies. With this technique, the music is transferred off the CD original via a computerized disc drive. Then the recording is burned or transferred to another specialized recordable CD, called CD-R or CD blanks, etc.

You can select three kinds of CD blanks with this process. Older styles of stereo systems and computers can play the CD-R discs. The more recent car and home stereos, DVD players and computers will read either of the CD+Rs or the CD-Rs. Select the plus or minus according to your intended target group. CD-RWs just are discs that can be recorded on more than once. The material placed on it can be erased. This makes the disc ready to be used once again.

Occasionally, the duplication process will uncover a blank CD that was not properly created. These CDs will fail to record information at all on them. They will still be registered as blank when finished.

Although, the CD replication technique provides a slightly, very slightly, better end product, the cost can be high for low quantity runs. The CD duplication technique will not take long, is inexpensive, and turns out a very nice product.
