Lucent launches holographic storage venture

Lucent Technologies Inc. Wednesday revealed its commitment to multilayer storage technology with the formation of a new company called InPhase Technologies.

InPhase Technologies will continue development of Lucent's holographic storage technology. Instead of recording data on the surface of a disk, the technology will enable the recording of data through the entire thickness of the storage medium, which should allow for greater storage capacity, officials said.

Developed by Lucent's research arm, Bell Laboratories, the technology also stores data in what officials called page format, which can be accessed one million bits at a time for faster data retrieval.

Lucent officials have not set a date for the first holographic storage products to arrive.

Storing information on more than one layer of a disk is far from a new idea. In November 1999, C3D, based in New York, introduced its Fluorescent Multilayered Disk, a storage disk with as many as 50 fluorescent layers designed to hold nearly 10GB of data. The C3D technology that discriminates between the different fluorescent layers to read and write data is still in development.
