Abstract
Several models, such as the Stoner-Wohlfarth (SW) model and the curling model, have been proposed for calculating the M-H curves of magnetic recording media. We created a new magnetization model and used it to calculate the M-H curves of both perpendicular and longitudinal media. The equation reproduced the M-H curves with small values of Hc/Hk for both types of media by use of a value of exchange interaction in a particle as a parameter.
