Signal output from a small piezoelectric transducer bonded to a flying head slider is analyzed. Slider-core natural vibrations and slider rigid body oscillations are identified with the frequency peaks of the signal output. These analyses are applied to a highly sensitive contact detection and an evaluation of dynamic characteristics of a slider on a real medium.
