Micromagnetic modeling of small dimension magnetoresistive (MR) heads is reviewed. Recent simulation results are presented, pertaining to recording applications with high areal density nearing 1-10 Gb/in/sup 2/. The proper biasing and reproduction properties of the most interesting MR head configurations have been studied, in order to achieve design optimizations for ultra-high density MR heads. Initial comparisons between the performances of a shielded MR-SAL head and a dual MR head are obtained.>
