Hard Disk, the final frontier, all the world’s books in a postage stamp – The Messenger

 (AGI) – Imagine opening your computer desktop and to remove the hard disk contained therein. You will have in his hand a great little box like a book or a thin pack of cigarettes. The technology that makes it up is mixed, a little ‘e and so much made of motor mechanics, metal plates, screws and supports that jars with the futuristic idea that we have computers. If, instead, we bought more recently our PC, and pagatolo a bit ‘more handsomely, the mechanics is gone and the storage device has reduced even more dimensions to become a tiny circuit board. Losing the mechanical part, although we continue to call them hard drive, it has been, for mass storage devices, on the one hand a “release” from factors such as power consumption and the other an increase in performance in terms of speed d ‘ access to data. Researchers at the Kavli Institute of Nanoscience at the University of Delft, in the Netherlands, have shot down another frontier failing to provide data storage capacity 500 times higher than the best hard drives currently on the market. In terms of space, then, that would mean writing the whole humanistic production, the contents of libraries around the world, a stamp or a little more. Everything is based on still under study nano-technologies and then relegated in the labs, remote from industrial production. What is behind all this is a technique that operates on the atomic scale: a copper film is covered with a layer of chlorine nonoatomico according an ordered pattern, a chessboard. The arrangement of the chlorine atoms on the board, bringing them closer or deleting them, as in a micro atomic QR Code, is representative of a quantity of information. The spatial repetition of the basic configuration of the chlorine atoms, or its absence, is the way of representing the amount of information in a infinitesimal. A “super mini hard disk” has in theory infinite capacity and consumption of the order of watts. Imagine, now, what might become the computing centers around the world freed from energy and space limits. What a change that clashes with the current limitations: the atomic hard drives and operates vacuum to -200 ° C. But even when Jules Verne in “From the Earth to the Moon” had predicted the Neil Armstrong walk there was talk of science fiction, and then…
