The dynamic response of a flying head slider due to a rectangular bump is simulated numerically by solving the modified Reynolds equation directly in the time domain. The response is also measured accurately using visible laser interferometry. The experimental results agree well with the numerical results, both indicating a wide range of movement. As a result, the modified Reynolds equation is confirmed to be quite suitable for an accurate prediction of the slider dynamic response even at a low flying height. Furthermore, the ordinal perturbation method is compared with the direct numerical simulation method and the differesces between both methods are clarified.
