These days one often gets to hear about such terms as CD duplication, CD printing, DVD replication and so on. While it is easy to understand that these terms pertain to various duplication methods for popular optical media formats such as CDs and DVDs, the real distinctions are not very clear to most of us.
For example, many of us do not exactly know the difference between CD duplication and CD replication. Both are popular methods of making multiple copies of the CD media, but there are important differences between them. One should always be aware of them to be able to select the right kind of services for specific requirements.
The duplication method, best suited for low volume requirements, involves direct writing of data onto blank CD-R media. Powerful commercial CD writers are usually used for the purpose that can write data simultaneously to multiple discs.
The replication method is a more complicated one. It is essentially based on the practice of creating a master mould first from which subsequent copies are stamped. Take the example of DVD replication .Typically, the process is best suited for large scale requirements ranging from 1,000 to 1,000,000 copies and involves transferring the original data to a glass master. This is then used to create a metal stamp that presses the data into plastic injection moulds, before a reflective layer of aluminum is coated on the back surface, allowing the CD player’s laser to read it.
Keeping these differences in mind will let you choose the best method of mass production of your digital media.
