Abstract

Decision support systems Magnetic analysis Magnetic domain walls Magnetic force microscopy Magnetic heads Magnetic recording Magnetic switching Magnetization Perpendicular magnetic recording Remanence
Longitudinal recording in its conventional form has been projected to suffer from superparamagnetic instabilities at a density of approximately 40 GbiL/in2 [I]. It is believed that changing the bit cell aspect ratio will extend the superparamagnetic limit of magnetic recording. Also, perpendicular recording might be extensible to higher densities due to a thicker optimum recording layer [2].
