Evaluating the dynamic contact force of an optical contact head slider is requisite in realizing its stable mechanical operation and higher readout performance. Continuous acoustic emission (AE) signal modulation propagated from a contact slider was carefully detected and compared with the applied out-of-plane acceleration on a medium generated by a spindle combined piezoelectric (PZT) actuator. It was clarified that the detected AE modulation amplitude was approximately proportional to the applied acceleration.
