You may not think there is a difference between DVD duplication and DVD replication. After all , each process produces the same result - a copy of the original disc. You could be surprised at the variations between the processes, though. The standard of one disc compared with the second is obvious when they're used for mass production.
DVD duplication is just that-duplicating a programme, motion picture or creative performance onto another DVD to share it with somebody or to market it commercially. Someone with a computer and a DVD burner can simply copy a DVD to a blank disc and produce an OK copy. However , this isn't normally done at home for big amounts as it is very time in depth.
Directors, home businesses and video production firms have all found copying little quantities of DVDs to be an effective way of promoting themselves. Copying a DVD of their work is useful to their careers and can be done on their home PC. Most huge run DVD copies are mass produced on a bigger scale than the typical person can manage. It involves several copies of the DVD, each copy connected to a bank of burners stuffed with blank DVDs so that lots of copies can be made in minutes. The information from the DVD is replicated by these burners so that an OK copy is produced.
However, DVD duplication isn't the same as DVD replication. Whereas duplication just copies the information from an original disc, replication involves more steps to insure the integrity of the final product. The first thing done in the replication process is known as pre-mastering ; the master disc is fastidiously checked to make certain that not one of the info is corrupted. When it is determined that the master is perfect, a glass master is formed so a stamper can be developed.
Stamping involves a mold for the DVD discs. An injection molding machine uses heated polycarbonate that is injected then briefly cooled before the information from the glass master is etched onto it. Because each disc is made of the same glass master that remains uncorrupted, a replicated DVD is typically of higher quality than a duplicated DVD.
Copying also includes adding protective layers to each disc to preserve the data. Duplication lays down the data on the disc without extra 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 single time a duplicated DVD can be problematic is if the disc is observed in a old standalone DVD player. In a few cases, these DVDs will not play. These issues aside, replicated and replicated DVDs are frequently indistinguishable and the DVD packaging available for both is the same.
