CD or compact disc is a plastic optical disc on which digital information is stored. A reflected laser light is used to read the data that is stored on a compact disc. When it comes to storing information in a cost efficient manner, then CDs are the best option you’ve got. Many instances arise where a large amount of data needs to be stored and multiple copies need to be made so that backup for that data is available whenever required. In such cases a particular CD is replicated so that various copies can be kept of a particular piece of data.

What is CD Replication?

CD replication is the process of producing multiple CDs containing the same information. It is a process in which the master CD; on which data has already been burned, is actually pressed through a glass master.This CD is often called CD ROM disc as it can only be read and not written on. ROM is the abbreviation of read only memory, and therefore, signifies as to why the CD is called CD ROM disc.

When the master CD is burned through the glass master, multiple replicas are made of the same piece of information; hence the term CD replication. The glass master consists of a piece of glass covered with a layer of chemical that has been burned off with laser. This is basically the “negative” of a CD. This glass is then coated with a compound of nickel, which converts it into a stamper. This stamper then punches tiny pits into the manufactured CDs, and thus, the replicating process is complete.

Once these CDs have been replicated, they are then printed through a 5 color silk screen which transforms them into high quality discs.

CD replication is actually a very efficient way of making copies of a master CD, however, it is not feasible for the production of small amounts of CDs as setting up a production facility for the replication of CDs requires a very high cost. It is perfect for CDs that need to be produced in bulk.
