In this paper, we describe an experimental study of the fundamental characteristics of bouncing vibration of a contact slider for future high-density hard disk storage. For the experiment, we made four different types of contact slider, composed of similar stainless steel beams and glass or lead balls. Vibration of the slider is measured using a laser Doppler vibrometer. The measured data are analyzed by an FFT analyzer. From the experiment, it is found that the bouncing vibration is always low when the slider load is high, the coefficient of restitution is low and the slider beam damping is high. In the lead contact sliders, the bouncing vibration is smaller for smaller mass. However, in the case of some glass sliders, a large mass can reduce the bouncing vibration because of the increase in the inertia effect. Almost all experimental results qualitatively agree with the theoretical ones. However, we also observed new resonance phenomena in the low-frequency range.
