基于传输线模型设计和分析了，一种新型的相互自偏屏蔽磁阻头（ＭＲ）。对信号场分布，输出电压，谐波信号和磁电阻作为偏电流，记录位移和时间的函数进行仿真模拟，结果表明该磁头的线性工作电流在１０～３０ｍＡ之间，在总缝宽Ｇ０小于０．６μｍ的条件下，不仅具有较好的高频线性响应特性和完全对称的再生信号输出波形，而且有高达４５％的效率。这些结果对提高计算机硬盘的记录密度是很有意义的。
Based on the transmission line model design and analysis, a new type of mutual self-shielded magnetoresistive head (MR). The distribution of the signal field, the output voltage, the harmonic signal and the magnetoresistance are simulated as a function of the bias current, the recording displacement and the time. The results show that the linear working current of the head is between 10 ~ 30mA and the total slot width G0 is less than 0 .6μm conditions, not only has good high-frequency linear response characteristics and completely symmetrical reproduction signal output waveform, and up to 45% efficiency. These results are significant for improving the recording density of computer hard disks.
