磁光存储系统中，存储信息的介质———磁光材料膜的读／写性能直接影响了系统信噪比和信号质量，直接擦写等性能指标，因此，研制和开发高性能磁光材料是改善系统性能的直接手段。本文介绍了一个磁光材料读／写性能测试系统以及利用该装置对大克尔角磁光材料ＭｎＢｉＡｌ样品进行的静态读／写试验，测试结果可以为分析和改进这种新型磁光材料的读／写性能及其实用性提供有益的数据
Magneto-optical storage system, the storage medium of information --- magneto-optical film read / write performance directly affects the system SNR and signal quality, direct erase and other performance indicators, therefore, research and development of high performance magneto-optical material Is a direct way to improve system performance. In this paper, a read / write performance test system of magneto-optical material and static read / write test of the sample of kali photodetector MnBiAl with the device are introduced. The test results can be used to analyze and improve the readability of the new magneto-optical material / Write performance and its usefulness to provide useful data
