Understanding The Complex Process Of CD Replication

For many potential customers, understanding the process of CD replication can be a little difficult. Many people believe that replicating a CD is a straight forward task similar to burning a CD-R in their computer. It is sometimes hard to explain to a customer why replication takes at least 7 days leadtime.

The most important thing to understand is that CD replication is a full manufacturing process carried out from raw materials. The main material used is polycarbonate plastic with a thin layer of nickel sandwiched in between. The set up stages known as mastering are quite technical and complex but once metal stampers are produced the actual pressing of the disc is quite fast.

It is the mastering stages that are the most time consuming. The glass mastering process is quite a speedy process but then the production of the metal stampers does take some time. The metal stampers are produced by using a form of electrolysis and this does usually take a few days. It is not really possible to speed up the electrolysis process and this part of the manufacture tends to govern the leadtime. It is not uncommon for the metal stampers to fail and when this happens the leadtime may extend by a couple of days.

Although this manufacturing process can take around 7 days the quality of the replicated CD is certainly worth the wait. A replicated disc will always have a longer lifespan than a CD-R due to the way the disc is produced.
