Replication and Duplication are two separate processes. Many times, people confuse the two with each other. Duplication is a cost effective method for producing smaller quantities of discs as opposed to producing a large quantity to be sold in retail stores across many different states or even countries.
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.
To “burn” a CD or DVD, the burner uses a write laser. This laser alters the surface of the discs by bouncing light off the dark dye that is in the recordable disc. The laser writes to the disc by moving outward as the disc spins. The burn rate is determined by the spin rate of the laser and todays burners can write CDs in excess of 50x and DVDs in excess of 16x.
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.
