Thermally Actuated

A computationally efficient five-degree-of-freedom dynamic model was developed to simulate the motion of a magnetic head slider under the conditions of moving-bump collision and of contact due to an expanding protrusion on the slider for thermal flying-height control, with consideration of intermolecular forces. Compared to results obtained without intermolecular forces for a bump on the rotating disk, the intermolecular forces cause a significantly greater normal contact force, a larger roll angle and a larger off-track displacement under nonzero skew. When an expanding protrusion on the slider reaches a position close to the disk surface, the intermolecular forces pull the slider into contact at an earlier time and keep the protrusion in contact for a longer duration, which, with friction under nonzero skew, results in a substantially greater off-track displacement.

Air Lubrication

The dust adhering to the taper of a slider changes the shape of its flying rail and decreases the efficiency of air lubrication that determines its flying height. The dynamic flying height characteristics of the slider with dust at its taper are numerically and experimentally examined. The numerical results show that a triangular accumulation of dust at the tapered portion of the slider degrades the motion-following performance of the slider as it covers the runout of the magnitude disk surface. A dust adhesion experiment revealed that dust at the tapered portion decreased the flying height and increased flying height fluctuations. The disk runout is considered a major reason for the fluctuation increase.
