Due to the limits of conventional perpendicular magnetic recording, it appears that
alternative technologies are needed at areal densities> 500 Gb/in 2. Heat-assisted magnetic …

In this paper, we present a review of the write and read processes in perpendicular magnetic
recording. We also discuss their impact, based on recording physics aspects, on design …

We perform multiscale finite element simulation of the write process in perpendicular media.
The Landau-Lifshitz-Gilbert equation is solved simultaneously for the head, the data layer …

A hard disk drive or other disk-based storage device comprises a storage disk, a read/write
head configured to read data from and write data to the disk, and control circuitry coupled to …

A Landau-Lifshitz-Gilbert (LLG) micromagnetic analysis using a parallelized program on a
