PROBLEM TO BE SOLVED: To provide an acceleration simulation method by accurately estimating acceleration temperature even when variation of axes of easy magnetization of crystalline particles is small and temperature dependence of a frequency factor cannot be ignored. SOLUTION: The acceleration simulation method for determining thermal relaxation process of magnetization of a magnetic recording medium by temperature acceleration is configured to use the acceleration temperature satisfying a predetermined relational expression for acceleration simulation. Accuracy is improved by expressing logarithm of the frequency factor as a polynomial related to temperature T. COPYRIGHT: (C)2011,JPO&INPIT
