Summary :

This letter describes the comparison of the impulse force detection method for a head slider and a disk medium using a small piezoelectric transducer (PZT) stuck on the head slider, with the method using visible laser interferometry. The experimental results for the signal level of the PZT agree very well with the acceleration measured from laser interferometry method. There is also good agreement between the spectrum of signal output of the PZT and laser interferometry, when the head slider flies over a rectangular bump made on a glass disk.
