We investigated an optimal design method of a head suspension with dynamic absorber that can suppress the flow induced vibration of suspension. We call this new suspension Dynamic Absorber Suspension (DAS), and numerically studied the effect of the dynamic absorber to suppress the flow-induced sway mode and 2nd torsion mode vibrations of a head suspension by FEM. As a result, we proposed a proper dynamic absorber design for suppressing the sway mode and 2nd torsion mode, and showed the suppressing effect of the sway and 2nd torsion modes. From frequency response function of DAS, we found that magnification factor of sway mode can be reduced 25dB, and that of 2^<nd> torsion mode is less than OdB by means of the additional mass of about 5% of suspension main body.
