Data Storage Breakthrough Could Store the Library of Congress on a Dust Mite

Using this new data storage technique, you could fit the entire Library of Congress on a cube smaller than a dust mite—or the size of George Washington's pupil on a one dollar bill. A team of nanoscientists led by Sander Otte at Delft University of Technology in the Netherlands has just unveiled the densest method ever developed to store re-writable digital data. By scooting around individual chlorine atoms on a flat sheet of copper, the scientists could write a 1 kilobyte message at 500 terabits per square inch.
