A dynamic two-degree-of-freedom contact with friction model of the head-disk interface (llD1) is presented accounting for slider thermal protrusion and its influence on the IIDI dynamics. Using this model, which includes roughness, the applied power to the thermal protrusion is calculated that leads to minimum flying-height modulations. The model predictions are verified by drive-level experimental results.
