Abstract
The design theory of the previously proposed contact head slider was extended by considering the intermolecular adhesion force and thermally protruding head slider.The microwaviness-excited vibration characteristics of the thermally protruding head slider were analyzed by using the JKR adhesive contact theory.An important fact revealed is that.owing to the adhesive force,the excited frequency of the contacting slider are changed from zero to a value higher than the original second mode resonance frequency with an increase in the head penetration depth.This results in the successive appearance of the first and second pitch mode resonances.It is suggested that the region of the head penetration depth for perfectly stable contact sliding can be widened by increasing the contact damping and decreasing the microwaviness.
