Glass Stamper

 CD and DVD Glass Mastering

The Stamper is a metalised glass master used in the injection moulding process to replicate CDs and DVDs in a precise manner.

Bulk-replication wears out the stamper which needs to be replaced at regular intervals. Painstaking effort is made to ensure consistency of each stamper. Maintaining the uniformity of the stamper is essential so exactly the same discs can be produced throughout the repeated replication process.

 

 

Stampers are made with a Glass Mastering Process.

Glass Mastering comprises a number of stages to create a metalised glass master from which stampers are produced. Information from a master tape is transferred to the glass via Laser Beam Recording. Subsequent development, metallisation and electroforming produces a nickel Father stamper.  

 

 

 

Our one stop solution service includes the manufacturing of a quality stamper for the mass replication of a client’s optical disc needs. We are capable of making more than 80,000 stampers per annum at Group level from our facilities in Australia (Sydney), Singapore (HQ) and China (Shanghai).

The Stamper is made with a Glass Mastering Process commencing with a piece of optically polished flat glass. The glass is spun and coated with a polymer dye to a specific thickness. It is then baked in order to produce a piece of glass with a polymer dye film on it, like a thin plastic film.
 
The data grooves are cut in the polymer dye combined with DRAW (direct read after write technology). Once grooving has finished, the glass master is layered with nickel applied by a vacuum deposition process. The nickel conductive layer is applied to enhance electrical connectivity in order to make the electroplating process work in turn producing a nickel Father stamper.
 
Our one stop solution service includes the manufacturing of a quality stamper for the mass replication of optical discs. We provide BD Mastering for both 1 layer BD25 and 2 layers BD50.
