Scientist working on 50TB DVD

Posted on Thursday, July 13 2006 @ 04:05:30 CEST by

An Indian born scientists in the U.S. is developing DVD's which can be coated with a light-sensitive protein and can store up to 50 terabytes (50,000GB) of data.
Professor V Renugopalakrishnan of the Harvard Medical School in Boston has claimed to have developed a layer of protein made from tiny genetically altered microbe proteins which could store enough data to make computer hard disks almost obsolete.

"What this will do eventually is eliminate the need for hard drive memory completely," ABC quoted Prof. Renugopalakrishnan, a BSc in Chemistry from Madras University and PhD in biophysics from Columbia/State University of New York, Buffalo, New York as saying.

The light-activated protein is found in the membrane of a salt marsh microbe Halobacterium salinarum and is also known as bacteriorhodopsin (bR). It captures and stores sunlight to convert it to chemical energy. When light shines on bR, it is converted to a series of intermediate molecules each with a unique shape and colour before returning to its 'ground state'.
