Abstract
There is provided a head suspension mechanism capable of more effectively restraining sway mode and second-order torsion mode vibrations of the head suspension mechanism caused by an air flow. A flange portion having a free end portion 23c on the base part side is formed at both edges close to the tip end of a suspension main frame 23, and at the same time, an elastic material 23d is provided in the free end portion 23c. Also, a sway mode dynamic vibration absorber is formed by the length of the flange portion and the damping effect of the elastic material 23d.
Claims8
A head suspension mechanism which supports a head slider rigidly in an in-plane direction and softly in an out-of-plane direction, comprising:
- a suspension main frame (23) having an elastic cantilever thin sheet extending horizontally to provide a load force to the head slider;
- a support portion (4) at a terminal end of the suspension main frame (23) to support the head slider;
- a flange portion (23b) at two opposite edges of the suspension main frame (23) near the support portion, the flange portions extending substantially vertically from the opposite edges;
- a tip end portion of the flange portion located near the support portion;
- a connecting portion at each of the two opposite edges of the suspension main frame (23) at the tip end portion, extending vertically from the opposite edges;
- and
- a free end portion (23c) connected to each of the connecting portions, each free end portion extending from an upper end of the connecting portion in a horizontal direction opposite the tip end portion to form an L-shape with a space between a lower edge of the free end portion and an edge surface of the suspension main frame (23), wherein
- damping material is provided on each free end portion, a dampening effect of the damping material and the length of the flange portion forming a sway mode dynamic vibration absorber.
