ABSTRACT:
A magnetic head suspension 10 has a flexure portion 18 constituted as a single one-piece structure with a load beam spring element portion 12. The flexure portion 18 projects beyond a distal apex of the load beam spring element portion 12. The flexure portion 18 includes a first connection arm member connected at a proximal end thereof to the distal apex of the load beam spring element portion 12. Head support means are suspended from the first connection arm member. The head support means are constructed and arranged for supporting a head slider bonded to one face of a bond pad area 26 thereof. The head support means has a pair of substantially parallel flexible longitudinal arms 28 substantially enclosing the bond pad area 26. The distal end of the flexible arms 28 flexibly suspend the bond pad area 26 of the head support means. The proximal ends of the flexible arms 28 are connected to the distal end of the first connection arm member. A stiffening member 20, adhesively secured to the load beam element portion 12 adjacent the distal end thereof, projects over at least a portion of the flexure portion 18 and has a load protrusion 22 projecting from a surface thereof for engaging the opposite face of the bond pad area 26, thereby increasing vertical axis stiffness and providing a gimballing point for facilitating tracking of the slider over the surface of a disk.
