成功研制了磁光记录薄膜擦写疲劳特性测试系统。系统中利用串联谐振法 ,获得了重复频率为 1 k Hz、峰值磁场达 4 0 k A/m的高频双向脉冲磁场 ,同时采用除法式读出消除了读出激光功率波动
Successfully developed a magneto-optical recording film erase fatigue test system. In the system, a high frequency bidirectional pulse magnetic field with a repetition frequency of 1 k Hz and a peak magnetic field of 40 kA / m was obtained by the series resonance method, and the readout laser power fluctuation
