Latest Patents

Walter R. Eppler holds a patent for "Optical disc stampers and methods/systems for manufacturing the same." This patent discloses optical disc stampers, methods of manufacturing these stampers, and systems for replicating optical discs using the stampers. The optical disc stamper is formed directly on a substrate that supports a patterning material, which includes 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, and unexposed areas 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 the removal of the unexposed patterning material. This optical disc stamper can be utilized in the replication of optical data storage discs. Additionally, systems for practicing the methods to produce optical data storage disc stampers are also disclosed.
