You may not think there's a difference between DVD duplication and DVD replication. After all , each process produces the same result – a copy of the first disc. You could be surprised at the differences between the techniques, though. The quality of one disc compared to the other one's clear when they are used for mass production.

DVD duplication is just that-duplicating a programme, motion picture or artistic performance onto another DVD so as to share it with someone or to market it commercially. Somebody with a P. C. and a DVD burner can simply copy a DVD to a blank disc and produce an acceptable copy. this is not routinely done at home for large amounts because it is extremely time in depth.

Directors, small businesses and video production corporations have all found copying little quantities of DVDs to be a good way of promoting themselves. Duplicating a DVD of their work is useful to their careers and can be done on their home computer. Most large run DVD copies are mass produced on a bigger scale than the average joe can manage. It involves several copies of the DVD, each copy connected to a bank of burners loaded with blank DVDs so that hundreds of copies can be made in minutes. The info from the DVD is duplicated by these burners so that a satisfactory copy is produced.

However, DVD duplication is not the same as DVD replication. Whereas duplication just copies the data from an original disc, replication involves more steps to insure the integrity of the final product. The very first thing done in the replication process is named pre-mastering ; the master disc is meticulously checked to make sure that not one of the info is corrupted. When it is determined that the master is perfect, a glass master is created so that a stamper can be developed.

Stamping involves a mildew for the DVD discs. An injection molding machine uses heated polycarbonate that's injected then quickly cooled before the info from the glass master is etched onto it. Because each disc is made from the same glass master that remains uncorrupted, a replicated DVD is generally of better quality than a duplicated DVD.

Copying also includes adding protective layers to each disc to save the info. Duplication lays down the info on the disc without further physical protection, leaving it more prone to scratches and pits.

The average person will happily enjoy a duplicated DVD and not hear or see many noticeable differences. The one time a duplicated DVD can be tricky is if the disc is studied in an exceedingly old standalone DVD player. In some cases, these DVDs will not play. These issues aside, duplicated and replicated DVDs are frequently indistinguishable and the DVD packaging available for both is the same.
