磁盘机头—盘间隙测试仪

A Slider-to-disk Spacing Measuring Instrument for Magnetic Disk Driver

本文介绍了实际应用的HDS-PY1型头—盘间隙测试仪,其中包括基本原理、技术特性、典型应用及误差分析。该仪器给出头一盘间隙值1～5μm±2.5%的结果以及其它多方面的功能,为计算机工业中的关键设备——磁盘机研究与发展提供了实用的测试仪器。

A detailed description of a slider-to-disk spacing measuring instrument for magnetic d(?)sk driver is given, including the basic principle, the technical characteristics, typical applications and its error analyses etc. This instrument has been put into application. A slider-to-disk spacing from 1 μm to 5 μm and many other parameters may be measured by the instrument. This is a very practical instrument for research and development of magnetic disk driver-the key device of computer industry in China.
