Computer simulation of perpendicular magnetic recording has been carried out by applying the modified coherent rotation model (Stoner-Wohlfarth model) to the magnetizing process of a Co-Cr layer. The modification has been made so as to fit the calculated M-H loops in the measured loops for various directions of applied field. Using this model, the M-H loop of a sputtered Co-Cr film can be restored by calculation. The reproduced wave form of an isolated pulse and the bit density response obtained by the simulation using the modified S-W model agree well with measurements.
