World’s smallest storage device

worlds-smallest-disk

Scientists at Kavli Institute of Nanoscience at Delft University have built a nanoscale data storage device containing 1 kilobyte (8,000 bits) with a storage density of 500 terabits per square inch (Tbpsi), 500 times denser than the best commercial hard disk drive currently available. Each bit is represented by the position of one single chlorine atom.
