Analytical expressions for transition width and transition jitter in granular PMR media taking account of switching field distribution

We have reported analytical expressions for transition width and transition jitter based on the media micro-structure and the readback resolution. In most practical applications, the switching field distribution (SFD) cannot be ignored. In this work we derive analytical formulations that are good approximations for the transition width and transition jitter using Voronoi cell modeling with a finite SFD.
