1 序言软盘存储装置,在当今微机系统中作为简单、方便的辅助存储装置,正在广泛地使用,今后将会开发出体积更小,容量大,速度高的装置.在开发新机种时经常遇到的问题是磁头发出响声现象.这种现象比较复杂,到目前为止,谋求稳定的措施是错误的,因此,这种现象发生的机理,至今还没有搞清楚.由于磁头发出响声是一种不稳定的,复杂现象,因此,近年来,河野先生等人开始了系统的实验、研究,针对不稳定振动的特点,掌握了数百 H_z 程度的振动频率,并得到 1 INTRODUCTION The floppy disk storage device is being widely used as a simple and convenient auxiliary storage device in today’s microcomputer system. In the future, a smaller, larger and higher speed device will be developed. The problem is the sound of the head sound phenomenon.This phenomenon is more complex, so far, to stabilize the measure is wrong, therefore, the phenomenon of this phenomenon has not yet been clarified.Since the head is a kind of sound is not Therefore, in recent years, Mr. Kawano and others started systematic experiments and studies. According to the characteristics of unsteady vibration, they mastered the vibration frequency of several hundred Hz and obtained
