In order to achieve high-density recording, the detailed behavior of thermal degradation should be investigated. In this paper, the degradation of magnetization of high-density recording medium is examined using the 3-D finite element method (FEM) combined with the modeling of Stoner-Wohlfarth (SW) particles and Neel-Arrhenius switching probability. It is shown that the anisotropy field Hk suppressed the thermal degradation and the saturation magnetization Ms enhances it. The thermal degradation is also changed by the amplitude of magnetization.
