The World Smallest Hard Drive Is 96 Atoms Big
Scientists from IBM and German Center for Free-Electron Laser service have succeeded in creating the world smallest hard drive with the help of nanotechnology. The 96 atoms sized drive was deployed for one byte data, whilst presently billion of atoms is required for each byte. The smallest hard drive in the world was built with the help of Scanning Tunneling Microscope (STM) and a special form of magnetism known as anti-ferromagnetism, employed for data storage purposes for the first time. Without magnetic interference between each other anti-ferromagnetic atoms were spaced extremely closely and consequently, the scientists were capable to set bits only one nanometer apart.
