Akonia Holographics, LLC, Longmont, CO, has been assigned a patent (8,786,923) developed by Ernest Y. Chuang, Boulder, CO, Kevin R. Curtis, Longmont, CO, and Yunping Yang, Los Angeles, CA, for “methods and systems for recording to holographic storage media.”
The abstract of the patent published by the U.S. Patent and Trademark Office states: “According to one aspect and example, a method for recording holographic media and/or holographic master data masks includes recording at least a first hologram or information layer with a first holographic medium (e.g., a “submaster”) and recording at least a second information layer with a second holographic medium (e.g., a second “submaster”). The first information layer and the second information layer from the first and second holographic media are then sequentially reconstructed and stored with a single holographic master medium (e.g., a “master”). The holographic master may then be used to record the stored first and second information layers into additional holographic media, for example, into HROM devices or the like.”
The patent application was filed on May 17, 2005 (11/131,601).
