Understanding the process of DVD replication
DVD replication is the process of creating a disc from scratch. This is not the same as DVD duplication, which is essentially, copying the information on the DVD onto an empty disc.
Businesses which are looking to replicate a DVD should approach a DVD replication service for the task. The reason for this is that molds are required to produce the discs. DVD replication is most often used when a small number of discs have to be created, usually less than 500 units.
The first step of DVD replication is a process called "mastering." In this process a laser is used to copy data onto a light-reactive glass plate. The photosensitive glaze on the plate reacts to the heat of the laser and in the process copies the information onto the disc. The data gets copied onto the glass master during the process of CD replication as well as DVD replication is in binary form.
Since it is the information from the master that gets copied onto multiple discs during the process of DVD replication, care must be taken to see that the master is prepared carefully and is of good quality. A reliable DVD replication company will be able to assure customers quality of service.
The glass master, which is the first step of DVD as well as CD replication, is usually done in a clean room. A great deal of care is taken to ensure that the surface of the master does not get affected in any way. Any scratch to the master will affect all the DVDs that are made by the DVD replication company.
A lot of DVD replication services create a metal mold, which is usually referred to as a stamper, for creating more copies. In this process of DVD replication, each stamper is injected with a transparent plastic substance called polycarbonate. This surface is then finished with a coat of reflective material to make it suitable for playing.
DVD replication process is preferred by most companies to duplication as the quality of the product is much better. DVD replication offers greater consistency in production quality and disc playability than that achieved through the burning process.
CD replication is a complicated process that is best left to a CD replication company. The time required to manufacture a batch of CDs can take anywhere between two to four weeks.
