storage capacity of magnetic disk drives by constructing "3D towers" of information. The team from SPINTEC created these pillars out of bit-patterned media -- separated magnetic nanodots, each of which carries one bit of data. By layering the dots in specific formations, the team created a "multilevel magnetic recording device" with an areal density of two bits per dot -- twice what it started with. According to researcher Jerome Moritz, these findings could provide IT companies with a new way to circumvent physical limitations to their data storage capacities, allowing them to build up and over the vaunted one Tbit per square inch barrier. The team's full findings were recently published in the American Institute of Physics' Journal of Applied Physics.
