A part created by plating onto the 'mother' in the electroforming process. It is then separated from the mother and used in the injection molding process to create the clear plastic discs.
a workman whose job is to form or cut out by applying a mold or die (either by hand or by operating a stamping machine)
a digital mirror image of your master disc and is used in a press that takes plastics, metals and bonding agents to actually stamp an exact copy of your original master CD disc
an original used for mass replication purposes
A metal part electroformed from the mother. The stamper is then placed in a mold cavity for the replication of discs.
A master etched with grooves and address for the mass production of magneto optical disk substrates.
Since a glass master is too delicate to be used for heavy-duty disc production, durable metal molds called stampers are usually made for disc stamping or pressing.
The electroformed part made from a mother and containing a reversed data image of the final disc. Becomes part of a mold for the injection molding replication process.
The data-bearing removable "die" used during the injection moulding of a CD to imprint pits and lands into the polycarbonate substrate of the disc. In manufacturing CD-R media, instead of pits and lands, a continuous spiral is pressed into the substrate as a guide to the recorder's laser. The stamper is part of a "disc family" created in the mastering process.
A part created for use in the injection molding process to create the plastic discs.
A metal tool which creates the spiral ( groove) and is held in the injection mold.
