Differences between DVD duplication and DVD replication
You may not think there's a difference between DVD duplication and DVD replication. Of course , each process produces the same result – a copy of the original disc. You could be surprised at the variances between the systems, though. The standard of one disc matched against the other one's clear when they're used for mass production.
DVD duplication is just that-duplicating a program, film or creative performance onto another DVD in order to share it with somebody or to market it commercially. Someone with a PC and a DVD burner can easily copy a DVD to a blank disc and produce an acceptable copy. this is not normally done at home for large quantities because it is terribly time thorough.
Directors, small businesses and video production companies have all found duplicating small quantities of DVDs to be an effective way of promoting themselves. Duplicating a DVD of their work is useful to their careers and can be done on their home PC. Most huge run DVD duplicates are mass produced on a bigger scale than the average joe can manage. It involves a few copies of the DVD, each copy attached to a bank of burners piled high with blank DVDs so that hundreds of copies can be made in minutes. The information from the DVD is cloned by these burners so that a satisfactory copy is produced.
However, DVD duplication isn't the same as DVD replication. Whereas duplication simply 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 known as pre-mastering ; the master disc is meticulously checked to make certain that none of the information is corrupted. When it is determined that the master is perfect, a glass master is made so 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 data 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 often of higher quality than a duplicated DVD.
Replication also includes adding protective layers to each disc to preserve the information. Duplication lays down the info on the disc without extra physical protection, leaving it more susceptible to scratches and pits.
The average joe will happily enjoy a duplicated DVD and not hear or see many obvious 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 won't play. These issues aside, replicated and replicated DVDs are frequently indistinguishable and the DVD packaging available for both is the same.
