Claim:
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 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 ( 23 c ) 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.
