A new computational method which can easily evaluate the relationship between the magneto-optic Kerr rotation angle θK and temperature T is presented. As a practical example, using this method, we have obtained the numerical solution for the preferential quadrilayer structure, the solution is in good accordance with the experimental results. On the basis of the best reading laser power derived by this method, the optimum signal to noise ratio of the optic disk can be obtained.
