The principle and method of the method of removing the magneto-optical signal are studied. The analysis shows that the detection method is not affected by the fluctuation of the laser power and the change of the disk reflectivity, and improves the accuracy of the data readout. The experimental results show that, Than the differential magneto-optical signal detection is more suitable for static experiments.
