Slider Dynamic Flying Performance at Drive Level

抄録

As technology moves to proximity recording and Gb/in^2 areal densities, the in-situ flying height and the flying stability measurement of sliders are becoming critical issues in reliability control and tribology performance design of present disk drives. This paper reports a method, testing system, and results of the drive level slider flying stability measurement with slider itself as transducer. The setup is based on monitoring the capacitance of between slider and disk surface. The flying performance and flying stability of sliders were investigated systematically under different track seeking modes
