CD Duplication and CD Replication - What you need to Know

By Frank Freedom


When you know what the difference is between the CD duplication or replication processes, you know which one will serve your needs the best. You will need to consider three main things with having your project created professionally; the number of CDs you want produced, the time frame you need them in, and the look of the discs.

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 CD master for this technique is made in a unique manner. The desired sound goes into special recording equipment. This equipment makes a positive imprint of your desired sound onto the surface of a disc that is constructed of gold, glass or silver. Copies are made from these with special stamping equipment to make negative imprints. Injection molds are made from negatives to make positive imprints once again.

CD Replication produces a very high quality of sound. The injection molds produce duplicates in high numbers, which are then coated with a film of aluminum and a protective lacquer surface. Once these have been hardened with an ultraviolet light source, they are normally printed and your high quality duplicates are ready for 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 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.

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.
