H. Victora, Department of Electrical and computer engineering, University of Minnesota, Minneapolis, MN, USA.
Abstract: “The ultimate user area density of heat assisted magnetic recording is a very important issue for both industry and researchers. In this letter, we first propose two new algorithms to accelerate the recording simulation using general-purpose computing graphics processing units. Then we predict user area density with current technologies and those expected to be available in the near future. Micromagnetic simulation predicts a user areal density of 1.8Tb/in2 using 6nm thick FePt media, while perfect recording yields more than 3Tb/in2. Optimization of track pitch in the absence of track mis-registration increases these values to, for the case of perfect recording, 5TBit/in2.“
