| Abstract: | Amplitude detection method used in magneto-optic data storage system at present is rather sensitive to both amplitude noise and polarized noise. With theoretical analysis and computer simulation, it is shown that the new frequency method has strong power in eliminating the both kinds of noise, and frequency method is able to supply an effective approach to develop one kind of simple optics with high quality of readout signals and fast data transfering rate. |
