Abstract :
A modified slope model is proposed that allows a determination of the transition parameter and the cluster size for perpendicular recording. The presence of the field gradient in the down-track direction causes the clusters to be smaller in the down-track than in the cross-track direction. The results are in good agreement with micromagnetic simulations for a wide range of parameters
