General Electric Assigned Patent
Replication and formatting method and system for bit-wise holographic storage
By Francis Pelletier | November 24, 2016 at 2:34 pmGeneral Electric Company, Schnectady, NY, has been assigned a patent (9,478,245) developed by Ostroverkhov, Victor Petrovich, Ballston Lake, NY, Bonanni, Pierino Gianni, Loudonville, NY, Shi, Xiaolei, Niskayuna, NY, Ren, Zhiyuan, Malta, NY, Xia, Hua, Niskayuna, NY, Wang, Xuefeng, Schenectady, NY, and Wang, Xinghua, Clifton Park, NY, for a “replication and formatting method and system for bit-wise holographic storage.“
The abstract of the patent published by the U.S. Patent and Trademark Office states: “The present techniques provide methods and systems for recording micro-holograms on a holographic disk using a plurality of counter-propagating light beams in parallel. The parallel counter-propagating light beams overlap to form interference patterns on a data layer and over multiple data tracks in the holographic disk. Rotating the disk enables the parallel recording of micro-holograms over multiple data tracks, thus reducing recording time. Further, the illumination pattern may include illuminated spots and non-illuminated regions, such that each illumination spot may cover a relatively small fraction of the data layer plane, possibly controlling the depth spread of the recorded micro-hologram. In some embodiments, data in the parallel signal beams may be retrieved from a master holographic disk or may be modulated into the parallel signal beams.“
The patent application was filed on October 19, 2010 (12/907,824).
