An analysis of tilted magnetic transitions in magnetic recording media

A theoretical analysis of a transition is presented. The centerline of the transition through the media is tilted from the normal to the surface. For an isolated transition, it is shown that both the demagnetizing fields and the readback pulse shape are dependent upon the amount of tilting. For the case of sinusoidal recording, the tilting introduces an additional phase shift and amplitude reduction in the neadback signal. The signal amplitude reduction is shown to become oscillatory as the tilting increases.
