Blu-ray Duplication Process Just when people were beginning to figure out exactly how to duplicate CD-ROMs and DVDs, the mainstream media switches to the Blu-Ray disc. This shift has come as a result of more advanced technology that allows for higher quality viewing. DVDs were read by a red laser, which was far more advanced than the no lasers involved in VHS. Blu-ray discs on the other hand are read by blue lasers, hence the name.
What is a Blu-Ray? The benefit of the blue laser is that it reads at a shorter wavelength than the red laser, picking up on the more subtle pits and grooves imprinted on Blu-ray discs. The discs have more capacity for memory, allowing there to be infinitely more detail and content. As it is also compact and relatively inexpensive, it is a viable option for mass production and duplication.
The Blu-Ray Replication Process All of these processes are handled in a mass producing factory, worked by automated machines in order to not allow for any error. Blu-Ray replication begins with master copies which must be provided on a portable hard drive, unlike DVD masters. Then a glass master, or aluminum master disc, is created from that. The glass master is then used to stamp the information and content into the hot polycarbon. This allows the Blu-Ray player to be able to read the imprints on the discs. Another important aspect of the Blu-Ray replication process is adding the finishing touches at the end – the disc artwork. This is a simple process where images are printed on by either the screen or offset printing process. Overall, this task of Blu-Ray duplication is not to be taken lightly as it can be easily confused and messed up, which is an expensive mistake, also unlike the DVD replication process. If you are unsure there are many resources on the Internet that are able to provide detailed descriptions.
Why Blu-Ray and not DVD? As Blu-Ray players can still read DVDs but DVD players cannot read Blu-Ray discs, it would be wise to make the shift now from DVD player to Blu-Ray player. Not only are DVDs going the way of the VHS, but Blu-Rays are becoming increasingly less expensive and more accessible. Soon enough DVDs will be a thing of the past and you will not be able to watch anything at home without a Blu-Ray player. If you have ever compared the abilities of the Blu-Ray and the DVD you know that there is no comparison and that the blue laser does clearly make a difference. Becoming aware of how the duplication process works will allow you to understand the
simplicity and instantaneousness of the whole process. It does not take long for a Blu-Ray to be duplicated, which allows for a quick distribution process which is absolutely necessary for mass production. Once you have the proper equipment, you will even be able to burn Blu-Ray discs from your home, just like you are able to with CDs and DVDs. Photo Credit: Gastonmag, Ambrozjo
