Abstract :
Summary form only given. Further reduction of magnetic head-disk spacing towards 8/spl sim/10 nm will require proper testing tools for in-depth experimental analysis of 3 dimensional dynamic stability of the slider in both the track following process and the load/unload process. The authors proposed and developed a novel flying height-attitude testing system that measures flying height simultaneously at three desired locations on the slider surface.
