磁头是磁性记录装置中的关键元件,工作时利用磁头进行电磁转换。记录时磁头将电信号转化为磁信号记录在记录媒体上,重放时又将磁信号从记录媒体上,取出转化为电信号。因此,磁头的好坏将直接影响磁记录的效果,这就要求我们必须设计制造出高质量的磁头,以满足工程技术上的需要。在实用中,要做出符合理想的磁头是不容易的。这里,一方面是因为对磁头材料以及加工、装配工艺要求高;另一方面,对磁头设计计算,还拿不出一个比较精确的方案,主要还是靠实验试制。所以,探讨磁头设计计算的方案,就显得非常重要。在设计磁头时,必须根据磁性记录的原理和工程要求考虑问题,例如:是录音、录 The magnetic head is the key element in the magnetic recording device, and the magnetic head is used for electromagnetic conversion during work. During recording, the magnetic head converts the electrical signal into a magnetic signal and records it on the recording medium, and in turn, the magnetic signal is taken out of the recording medium and converted into an electrical signal. Therefore, the quality of the magnetic head will directly affect the effect of magnetic recording, which requires us to design and manufacture of high-quality magnetic head to meet engineering and technical needs. In practice, to make the ideal head is not easy. Here, on the one hand because of the head material and processing, assembly process demanding; the other hand, the head design and calculation, can not get a more accurate program, mainly by experimental trial. Therefore, it is very important to explore the scheme of head design calculation. In the design of the head, the principle must be based on magnetic recording and engineering requirements to consider the problem, for example: is recording, recording
