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
