that’s a lot of space on one DVD. how much? it’s a bit hard to grasp. but 50 terabytes is the same as 51,200 gigabytes, or rather equivalent to 10,893 DVDs (@ 4.7 gigabytes each). completely amazing. these super high capacity DVDs it seems are closer to reality. Professor V. Renugopalakrishnan of the harvard medical school developed a disc with a layer of genetically altered proteins called bacteriorhodopsin that makes the mega-storage 50 terabyte DVDs possible. the proteins are only nano meters across so a lot can fit on the surface of a DVD disc. when light shines on bacteriorhodopsin, it is converted to a series of intermediate molecules - each with a unique shape and colour before returning to its original form or ‘ground state’. this is the basis for the binary code for such storage, with the molecular conversion of intermediate molecules being the one and the ‘ground state’ being the zero. Prof Renugopalakrishnan and his colleagues genetically modified the DNA that produces bacteriorhodopsin protein to produce an intermediate state that lasts for more than several years. the finding were presented at the 2006 International Conference On Nanoscience and Nanotechnology. there is more to read about it from articles on engaget and also digital video guru.
Hi,
I am a researcher with the protein program and was working with Dr. Renu.Motorola has a high level research facility where the same research is being pursued by my team and believe it when i say 50 tb is only a scatch on the surface of wht could be achieved
Hi!
This is interesting. how long ago was this being done? When will it hit the market ? At what stage is your research? thx
wow
This is amazing technology, and trump, your right, this is only the start, think of adding layers to this thing, but i dont believe you work for this project
