The method of creating several quantities of CDs is known as CD replication. This process is largely used in the music industry to replicate CDs and release music albums.CD replication is considered as a cost effective method by many media companies and production houses, who make large use of this process.The process of CD replication:The CD replication process involves making all the necessary adjustments to songs. In CD replication, the original CD is used to create the glass master- which means creating replicas of the master copy. When the glass master process is complete, the recorded information is layered with polycarbonate plastic. Once complete, they are screened one by one and their quality is tested.The next step of CD replication is the moulding. Hi-tech injection moulding is used to make copies using stamps.When copies are ready, it is necessary for them to undergo finalisation. During the process of finalisation, the CD is covered with aluminium and lacquer. This is then applied to help protect the surface and keep the data safe.At the end of the CD replication process, CDs are packed and distributed.
