近代磁记录技术一直是向着高记录密度、高使用频率方向发展。磁记录中关键的电磁换能器件-磁头也必然是围绕着这一方向不断开发并完善其性能。根据磁记录原理可知,影响磁头性能的因素是多方面的,但其中重要的因素之一是磁头铁芯材料的各项物理性能。比如:材料的初始 Modern magnetic recording technology has been toward a high recording density, high frequency of use of the development. The key electromagnetic transducers in magnetic recording - heads must also evolve around this direction and refine their performance. According to the principle of magnetic recording we can see that the factors that affect the performance of the head are many, but one of the important factors is the physical properties of the head core material. For example: the initial material
