| Popis: | An analytical model of the contact vibration of sliders was developed in order to determine the optimum specifications for minimizing the fluctuations of flying height. In this model, the motion of the slider is expressed with two degree-of-freedom in the translation and pitching directions. The air film and suspension are modeled as a two-degree-of-freedom mass-damper-spring vibration system; the contact force between the slider and the disk is modeled by integrating the contact area when the slider is in contact with the media at a certain pitching angle. The degree of interference when the slider is in contact with the media is modeled in terms of the interference height. The developed analytical model shows that the contact vibration of the slider has a divergent mode or a convergent mode depending on the magnitude of the coefficient of friction. These numerical results agree with our qualitative measurements of vibration. |
