| Abstract: | Magneto-optic readout process in frequency domain has been analyzed in this paper. A new method-real time frequency analysis method has been developed, which can conveniently measure the micro-beam parameters in magneto-optic storage system. The analysis of errors indicates that the method is simple and has high accuracy. |
