Abstract

PROBLEM TO BE SOLVED: To achieve stable float of a magnetic head by providing bent parts at a plurality of points of a load beam to apply a required depression load to a slider of a suspension integrally constituted of a flexure and the load beam, reducing a bump height, and lowering a vibration gain at a resonant frequency. SOLUTION: Bent parts C and D bent downward to a flexure 4, namely, to a slider 5 are formed at two points of a point A adjacent to a mount plate 3 of a load beam 2 of a magnetic head suspension. In the suspension 1 having the bent parts C and D formed at the load beam 2, in a state where a load is applied, that is, the slider floats, a bend angle is small at each of the bent parts C and D, and therefore bumps are lowered in height suitably as a whole.
