一、概述 磁头材料主要指用于磁记录系统的磁头芯片材料。磁头是磁记录系统的“心脏”其性能优劣不仅影响信号系统指标高低,而且影响电路系统结构繁简,机器调试的难易。磁头芯片材料的电磁特性是磁头性能优劣的关键。所以磁头芯片材料成为磁头设计者和材料研究工作者关注的中心。 随着磁记录技术向着记录密度、高保真度和小型化的方向发展。对磁头材料的要求也越来越高,如盒式录音机磁头发展由单声道→双声道→四声道,其高频段由几KHZ
I. Overview Head material mainly refers to the magnetic recording system head chip material. The magnetic head is the “heart” of the magnetic recording system, which not only affects the quality of the signal system, but also affects the complexity of the circuit system and the ease of machine debugging. The magnetic properties of the head chip material is the key to the merits of the head performance. So head chip material becomes the focus of head designers and material researchers. With the magnetic recording technology toward the recording density, high fidelity and miniaturization direction. Head material requirements are also getting higher and higher, such as cassette recorders head development from mono → dual → four-channel, the high-frequency by a few KHZ
