Media Duplication Explained

By Duplication Guy

The term Duplication is often confused with replication. Both are very different methods for producing duplicated CD or DVD media. Duplication is usually used and more cost effective when you have smaller amount of discs to produce. Replication is usually used for quantities of 1000 or more because of the glass mastering process involved.

The duplication process uses a premade blank disc as opposed to replication which uses a glass mastering process and actually stamps the discs out of the master. With duplication, you are able to burn a CD or DVD on your local PC. Replicating a disc on your local PC is not possible.

Duplicating a disc uses a burner capable drive and alters the surface of the blank disc by bouncing a laser off the dye in the disc. As the disc spins, the laser writes outward and the spin or burn rate is determined by the burn rate of the drive doing the writing.

Almost all DVD burners are dual purpose and will burn a CD or DVD disc. Discs are marked as CD-R, DVD-R, CD-RW, DVD-RW. There are other varieties but the one constant in them is the R or the W. The R shows that the disc is recordable and the W shows that it is writable and can be written to numerous times. The only problem with rewritable discs is that most often they will only play in the drive that originally wrote to them. Recordable discs however will usually play on any drive they are used in.

Mediatechnics uses their own line of equipment to duplicate CD and DVD media for small or large jobs. They have the capacity to turn any size job as quickly as needed.
