Efficient techniques for the computer simulation of magnetic recording in complex layered materials
Abstract
A technique for improving the efficiency and accuracy of simulations of perpendicular magnetic recording technology was discussed. It was found that the method was designed to improve the accuracy and scaling of the calculation of the demag field in layered, granular magnetic materials. It was observed that the speed, accuracy and parallel efficiency of the method was demonstrated on supercomputer and PC clusters. Analysis shows that the method and AYM software were used to perform an example simulation of perpendicular magnetic recording, writing a 'tribit' in a grained data layer.
