Summary:Magnetization reversal mechanisms for single patterned media elements have been examined. Sizes and magnetic properties have been examined for parallelepipeds of fixed aspect ratio. For element sizes for 1 Tbit/in2 recording magnetization reversal is nearly uniform for a uniform applied field. For fields covering a small percentage of the element volume nonuniform reversal occurs and the reversal field increases at a much smaller rate than inversely as the volume covered
