Mastering / Galvanics

OK Media produces up to 2000 masters per month. Careful checking of your data takes place before the mastering process begins. If required, our copy protection experts can be called in to help at this stage.

Mastering

First the input data is copied onto the server. A round glass plate coated with a photo-sensitive film layer is exposed to a laser beam. After the exposure the master is developed. Data is now saved as „pits“ on the master which looks a bit like a waffle iron. Later these are read by the CD/DVD drive and converted into the corresponding data such as music or film. At the end of the mastering process the disc is metallised with nickel ready for the galvanic process.

We use 8x DVD glassmastering, the most highly renowned manufacturer of this type of equipment with all the latest optical technology and encoders to ensure the utmost quality. Our client will receive an exact copy of the data given to us. If modifications are necessary our pre-mastering will be happy to help.

Galvanics

During the galvanic process a „father“ is produced as further nickel is applied in an electroplating bath after which this nickel plate is separated. This father  with the same but inverse/negative structure as the glassmaster, is then used to produce the „mother“ using the same procedure. The mother is the basis for the manufacture of  matrixes (so called „sons“) whose structure is the final structure to be used as pressing matrixes after they are cut out and grinded down. They are installed in the injection moulding machine for multiplication.

Capacity

Two 3-cell-baths in both Nortorf and Boizenburg, equivalent to 100 Galvanos per day (during normal 2 shift manufacturing)
