ABSTRACT:
Optical disc stampers, methods of manufacturing the optical disc stampers, systems for manufacturing the optical disc stampers, and methods of replicating optical discs using the stampers are disclosed. The optical disc stamper is formed directly on a substrate that supports a patterning material including at least one layer of a first material and at least one layer of a second material. The first and second materials can include a metal and semiconductor. The patterning material is exposed to energy in selected areas. Unexposed areas of the patterning material are then removed, resulting in an optical disc stamper. The first and second materials can form an amorphous alloy in the exposed selected areas that remains after removal of the unexposed patterning material. The optical disc stamper can be used in the replication of optical data storage discs. Also disclosed arc systems for practicing the methods to produce optical data storage disc stampers.
