There are two ways to make DVD copies. You can make DVD copies by duplicating or replicating.

When a small number of DVD copies are required the method of duplication is more practical. There are two types of writers that can be used to make DVD copies:

A blank recordable disk, computer with a DVD writer and appropriate computer software are needed with the first type of DVD writer. The DVD that contains the information that is to be duplicated is inserted into your DVD drive. The information is then temporarily copied onto your hard drive, and eventually to the blank recordable disk after your original DVD is ejected from the DVD writer.

There are also DVD duplicators that function independently without the use of a computer. DVD duplicators have several optical drives including a reader drive where the master disk is inserted. Blank disks are then placed onto the other drives to prepare for the duplication process with a touch of a button; the DVD master instantly copies all data into the blank DVD disks.

The amount of time it takes to duplicate a DVD depends on the DVD writers speed and the size of the files to be copied.

DVD copies that are produced in large quantities are done through a method called replication. Certain materials and machines are required to make DVD copies. First, the data of your DVD is stored into a glass master. The glass master is used to make a metal mold or stamper and is attached into a molding machine. A special chemical is then poured into the machine, which produces the DVD disk with the replicated information stored onto the disk.

There is no difference in the quality of DVDs that are produced by duplication and replication; however, some DVD players have trouble playing back disks that are copied through duplication.
