A simple model to predict the effect of medium orientation of longitudinal media on the transition sharpness is reported. It is shown that a traditional slope model can be suitably modified by multiplying the total field gradient with the medium squareness to reflect the loss in effective field gradient due to reversible magnetization rotations. The results agree well with experimental data.
