In a development that could revolutionize the way in which entertainment content is distributed to consumers, IBM unveiled today (Friday) breakthroughs in the field of nanotechnology that will eventually permit more than a trillion bits of data to be stored on a device no larger than the size of an iPod. The work, published in the journal Science, IBM scientists described progress in studying a "magnetic anisotropy" in atoms -- the ability of a single atom to store information. The work of the IBM researchers could eventually be incorporated into developing memory devices on a molecular scale that could store 30,000 feature films or the entire contents of YouTube on a tiny device.
