摘要

设计了一种热阻测试头，该测试头使用嵌入在空气轴承表面(ABS)的热电阻。感应电流产生的焦耳加热在头盘间距上产生热流，该热流高度依赖于ABS与盘之间的距离。由于位于滑块四个角上的热传感器，可以测量俯仰，滚转和飞行高度的变化。

Thermo-resistive flight attitude measurements of flying heads in near field magneto-optical data storage

A thermo-resistive test head that uses thermo-resistors embedded in the air bearing surface (ABS) was created. Joule heating by the sensing current generates a heat flow across the head-disk spacing which highly depends on the distance between ABS and disk. Due to the thermal sensors located on each of the four corners of a slider, pitch, roll, and flying height variations may be measured.
