ABSTRACT:
The invention provides a magnetic head suspension of an integrated wiring arrangement type which has an increased mechanical property and which may be produced at high yield efficiency. The invention eliminates bowing or warping from stainless steel plate subsequently constituting load beam or flexure, by obviating the step of unwinding or winding stainless steel plate. In a magnetic head suspension according to the invention, a flexure 2, having a thickness less than that of a load beam 1 and a rigidity less than that of the load beam 1, is bonded to one surface of the load beam 1, having a predetermined rigidity, through a bonding layer 14 of a flexible resin. An insulation layer 71 of a flexible resin is formed on the surface of the flexure 2 opposite to the surface facing to the load beam 1. The insulation layer 71 extends from the proximal end portion of the flexure 2 to the distal end portion of the flexure 2. A wiring arrangement 4 is formed on the insulation layer 71. The wiring arrangement 4 is connected to a magnetic head slider disposed at the distal end portion of the flexure 2.
