Smallest hard disk to date writes information atom by atom

Every day, modern society creates more than a billion gigabytes of new data. To store all this data, it is increasingly important that each single bit occupies as little space as possible. A team of scientists at the Kavli Institute of Nanoscience at Delft University reduced storage to the ultimate limit: They stored one kilobyte (8,000 bits) representing each bit by the position of a single chlorine atom. "In theory, this storage density would allow all books ever created by humans to be written on a single post stamp," says lead scientist Sander Otte. They reached a storage density of 500 Terabits per square inch (Tbpsi), 500 times better than the best commercial hard disk currently available.
