CD/DVD/Bluray Replication vs Duplication

CD/DVD replication and duplication are quite different when it comes to your company's image. Optical discs are made up of a number of layers. With replicated discs, a glass master "the father", is created with little pits. This is used to create a metal master "the mother". When melted polycarbonate is injected under high pressure and temperature onto the metal stamper, the bits of information are formed, creating a clear polycarbonate plastic which makes the first layer of a CD or DVD. Data is stored from the inner ring (the boot sector) to the edge of the DVD. The laser, reading from the underside of the disc will reflect and it will take more time to reflect back if there is a pit. This is then translated into 1s and 0s. Above the polycarbonate plastic layer is a reflective layer of aluminum. On top of that is a layer of acrylic, and then the label, which is often silk-screened or offset printed directly onto the acrylic. Replicated discs are pressed out at high speed and high volume, making them quite a bit cheaper for large volumes

CD/DVD/Bluray Replication and Duplication

Replication

Duplication



Duplicated discs have data "burned" onto them by a laser burning the dye on a prepared surface. Duplicated DVD or CD discs usually use inkjet or thermal printing. The big difference is that replicated DVDs will work on all players whereas burnt DVDs will work in a maximum of 99% of players. This may not seem like a problem until you get a call from a customer complaining about the low quality of your DVD because he cannot play it... or even worse, no phone call.
