The CD Replication Process


Do you wonder how we replicate CDs? Here is a very informative 3-minute video (by CDRom2go) showing how CDs and DVDs are replicated. For those of you who want to know a bit more, read the CD replication process below.

Pre-Mastering

To ensure that the data supplied by the customers meets the proper standards, we check how the contents of their CD-Rom are organized and try to edit it to perfection.

Glass Mastering

Afterward, we make a glass master that is covered with a photosensitive layer where the customer’s album details can be engraved by laser light.  This is performed in a self-enclosed clean environment within the mastering system in order to prevent errors. It is called Glass Mastering because glass is used as a substrate to hold the CD master image while it is created and processed.

Electroforming

Now that we have ensured the quality with Pre-mastering and made a copy thru glass mastering, it’s time to make a ‘mould’ by the process of Electroforming. We need to make the ‘mould’ sturdier and this can be done by adding a layer of nickel on the glass master by means of electrolysis. We then separate the nickel layer from the glass base to recover the negative of the CD to obtain what is called the stamper.

Replication

Now that we have created the mould, it’s time for the actual replication where we mass produce CDs in large quantities. Liquefied polycarbonate is injected into the mould and a compact disc is created containing exactly all the data that’s in the master. It just takes a few seconds to finish a CD unlike when you burn CDs using your own computers that would take minutes.

Metallization

So the information on the CD can be read by players, it should be covered by a very thin layer of aluminum. The aluminum coating serves as a mirror which bounces back the laser light so the CD will be readable.

Varnishing & Printing

The CD is coated with a layer of varnish to make it less susceptible to scratching and scratching. The lacquer envelops the aluminum and seals it from the elements to make the CD less fragile. Afterward, the CDs are ready for printing. The artist’s name, texts, logos, and many others are stamped on the CD. This is usually done with a silkscreen.

CD Packaging

Now that the actual CD is done, it’s time to place each CD manually in a CD packaging that the designers have made beforehand. The quality of each will be checked and then shipped to your homes.
