磁头/磁盘系统静态特性实验研究

Experimental research on performance of head/desk system

通过实验来研究磁盘转速对磁头飞行姿态和磁头读写性能的关系。研究表明:磁头滑块飞行高度和俯仰角伴随着磁盘转速的增大而增大;磁盘转速增大,磁头飞行高度增加,降低了磁头读出信号的能力,与此同时,信噪比也大幅下降。实验研究结果为磁头/磁盘结构设计提供了依据。

By experiments an investigation into the relationship between disk speed and the flying attitudes or reading and writing performance of magnetic head during the operation of hard drive has been performed. Experimental results show that the flying height of the magnetic head and pitch angle increases as the disk rotational speed increasing; the increasing of flying height of magnetic head lowers the ability to read the signals, and drops drastically the ratio of signal to noise. These results propose how to design the structure of head/desk system.
