ABSTRACT:
A plate member is made of a metal material lighter than stainless steel in a suspension for a head slider. This leads to a reduction in the weight of the suspension. The natural frequency of the suspension is thus raised. Moreover, the viscoelastic member is interposed between the front surface of the plate member and the back surface of the flexure. This structure allows either the plate member or the flexure to act as a base and the other to act as a constraining member. In other words, the plate member, the flexure and the viscoelastic member in combination act as a so-called vibration damper including constraining layers. The viscoelastic member serves to further suppress vibration of the plate member and the flexure.
