Simulations of MFM images of longitudinal thin films with low coercivity grains

The recording density of thin film media is affected by percolation within the transitions; such percolation has been shown to occur in areas where clusters of low coercivity grains lie. In this paper we present simulated Magnetic Force Microscopy (MFM) images which show it is common for inter-penetration between adjacent written bits to occur close to such clusters.
