Researchers from the Ecole Polytechnique Federale de Lausanne (EPFL) report what they believe to be the ultimate density limit of magnetic recording. The group created a self-assembled lattice of non-interacting two-atoms-high "islands"of cobalt on a single-crystal gold substrate. The islands' density, 26 trillion islands per square inch, is the highest yet recorded and 200 times the bit density of current computer hard disks. The magnetic properties of the islands are also the most uniform ever recorded.
