In order to compute the vectorial magnetization process of a crystalline particle in a Co-Cr sputtered film, a magnetization reversal model was investigated. A curling mode and a statistical method were introduced for the calculation of a probable vectorial magnetization of the particle. Using this method, the M-H loops of Co-Cr films were restored well by computer. Simulation of the perpendicular magnetic recording process was carried out in good agreement with the measured reproduced waveforms.
