DVD replication / DVD duplication CD replication

Whom would have thought 30 years ago that you could fit the contents of the entire Encyclopedia ( 200 odd KGs of book , occupying a certain large area of space ) on an object that is 12 cm across and was a couple of mm thick ? Suggest that and you might have been given some pretty strange sort of looks. But here we are 2009 and it is common place with the advent of DVD technology.  Now within 15 mins using the process of DVD Duplication you can move and copy a  massive amount of information with a few mouse clicks.  The process of DVD Duplication is something that was not so long ago a science fiction technology. Now with the advent of Blue ray disks the data limits are now at amazing capacties. The format offers more than five times the storage capacity of traditional DVDs and can hold up to 25GB on a single-layer disc and 50GB on a dual-layer disc. 

To ensure that the Blu-ray Disc format is easily extendable (future-proof) it also includes support for multi-layer discs, which should allow the storage capacity to be increased to 100GB-200GB (25GB per layer) in the future simply by adding more layers to the discs

Over 9 hours of high-definition (HD) video on a 50GB disc.
About 23 hours of standard-definition (SD) video on a 50GB disc.
If you were putting text documents on here it would be a mind boggleing amount. You can also be sure that the amount of information on these disks is going to keep rising . There is no doubt that we will be talking TB of data the in the future.  Based on the human species holding it all together and becoming aware of the evolution of the evolution of thought and getting affairs on planet Earth in order.
