Silicon storage: That’s a lot of data!
Richard Feynman once said that all the information in all the books in the world could theoretically fit in a cube 1/200th of an inch on a side. Looks like he got it right, says Technology Research News. Reporting on advances in data storage, the magazine says researchers at the University of Wisconsin, Madison have demonstrated the successful use of single silicon atoms to represent the ones and zeroes that are modern data storage. The result, in theory, is the ability to store the equivalent of 7,800 DVDs in one square inch of material. Engineering limitations mean writing atomic bits is impractically slow at the moment. But the Madison work is a realistic analysis of bit stability and recording density, says one scientist who has examined the work.
