Electronics Weekly reports that Hitachi’s UK researchers have also developed a complimentary technology to the “Get Perpendicular” concept they’re touting for increasing storage capacity (areal density) on hard drives. Tunneling anisotropic magnetoresistance (which earns you a triple word score) takes advantage of a side effect of manganese doping. In less syllabic terms, it lets them shrink the drive head to a few tens of nanometers, which will work nicely with the newly perpendicular bits they’ll be reading.
