摘　　要： LTO制式的磁带机用于服务器上的数据储存,自推向市场以来,不断地推出新产品,并成为这个市场的主流产品。LTO3是第3代LTO产品,磁头为各向异性磁致电阻磁头(AMR),本文通过对磁头的关键参数进行优化设计,如磁致电阻材料NiFe、偏转磁场材料CoZrMo和屏蔽层的参数,获得了良好的性能,写信号的磁道磁场均匀,写电流、Overwrite、信号波形不对称度、输出电压和磁头的原始读错误率(Raw Read Er-ror Rate)等关键测试参数均能满足要求,产品已批量生产。 The tape drive with LTO format is used for data storage in server. Since it was pushed to market, new products have been continuously developed and LTO becomes mainstream now. LTO3 is third generation of LTO product which adopts Anisotropic magnetoresistive （AMR） heads. The key design parameters of magnetic heads, such as the parameters of the magnetoresistive material NiFe , soft adjacent Layer（SAL） CoZrMo and shields, are optimized. And a good performance of magnetic heads is achieved. The transitions on all magnetic tracks are uniform,the key testing function parameters, such as Write current, Overwrite, output voltage, Asymmetry and Raw Read Error Rate, all can meet requirements, the product has been mass produced.
