This IBM breakthrough might lead to storage capacity we can hardly image, but it also presents a challenge. We haven't realized the goals of the Semantic Web and searching 40 million web sites is a challenge. Now imagine the problems of content-addressable storage and information retrieval with the storage capacities mentioned in this article. "IBM has known for a long time that harnessing the "power" of magnetic anisotropy is the key to develop structures and devices of atomic and sub-atomic scales, which would later become for example the building bricks of incredibly small, but also incredibly "generous" storage equipments. So they've focused their attention on how to measure the magnetic anisotropy of individual atoms, an endeavor previously considered inaccessible. Measuring an atom's magnetic anisotropy is vital for isolating its capacity to store information, thus opening insights into quantum storage. In 1959, physics icon Richard Feynman, in a characteristic back-of-the-envelope calculation, predicted that all the words written in the history of the world could be contained in a cube of material one two-hundredths of an inch wide - provided those words were written with atoms. ... With further work it may be possible to build structures consisting of small clusters of atoms, or even individual atoms, that could reliably store magnetic information. Such a storage capability would enable nearly 30,000 feature length movies or the entire contents of YouTube - millions of videos estimated to be more than 1,000 trillion bits of data- to fit in a device the size of an iPod. Perhaps more importantly, the breakthrough could lead to new kinds of structures and devices that are so small they could be applied to entire new fields and disciplines beyond traditional computing."
