hypnosec writes "A team of researchers has managed to boost storage density on traditional magnetic platters as high as 3.3 terabits per square inch using a technique that relies on NaCl — table salt. (Comparatively, a recent 4TB Seagate drive had an areal density of 625Gb per square inch.) A research team used a technique called nanopatterning to create arrays of magnetic bits that have more regular features (PDF) than the current traditional, randomly distributed technique. Team leader Joel Yang compares the technique to a well known traveling trick; 'It's like packing your clothes in your suitcase when you travel. The neater you pack them the more you can carry.' Yang said, 'In the same way, the team of scientists has used nanopatterning to closely pack more of the miniature structures that hold information in the form of bits, per unit area.'"
