Abstract

The effects of skew angles on signal and noise are analyzed in two thin film disk media with different anisotropy orientation distributions by micromagnetic simulations. The recorded magnetization patterns with a thirty-degree skew angle are shown for the isotropic and oriented media. The cross-track noise profiles are calculated and analyzed in both media at a recording density of 2405 flux-reversal per millimeter. The fundamental peak signals are compared for two skew angles of zero and thirty-degree versus recording densities in the isotropic and oriented media
