磁盘机轴向偏摆测量

An Axiat Run-Out Measurement of Magnetic disk devices

本文叙述了磁盘机轴向偏摆的一种测试原理和方法,介绍了测试装置及软件设计。在3600转/分的磁盘上进行了大量测试,得到了磁盘机轴向偏摆数值、动态偏摆R曲线、速度V曲线、加速度A曲线及其相应的R、V、A最大值,并对测量结果进行了分析。为研制温彻斯特磁头及测试盘片性能提供了可靠的手段。

The principte and the method of axiat run-out measurement of the magnetic disk devices were described in this paper. The test equipement and the software design were presented. A lot of test on the magnetic disk devices with rate 3600 turns per minute was made.The value of axiat run-out the dynamic run-out R curve velocity v curve, acceleration A curve and their maximum value were obtained. The result of test were analysised, It provides the reliable way for the devolopment of winchester magnetic head and the test of the preformance of the disk.
