Abstract
A magnetic read write head suspension with integrated lead traces on the load beam act as the longitudinal support arms for a cross bar and tongue of a T flexure or Watrous type flexure.
Claims6
An integral lead magnetic head suspension for attachment to an actuator arm within a disk drive, said head suspension comprising, in combination:
- a load beam including a base region at its proximal end for attachment to an actuator arm, said load beam having plural conductive electrical traces patterned on a surface of said load beam, at least one of the traces being insulated from the surface of said load beam, said traces projecting beyond a distal end of said load beam to form a pair of spaced trace portions extending in a longitudinal direction of said load beam beyond said distal end of said load beam, said load beam also having a load protuberance located thereon adjacent the distal end thereof;
- and
- gimbal means having a tongue portion including a slider mounting surface to which a slider is to be mounted, said tongue portion supported for pivotal movement about a pitch axis by a cross leg that is spaced from said distal end of said load beam and interconnecting said pair of spaced trace portions projecting from the distal end of the load beam, at least one of said spaced trace portions being electrically insulated from said cross leg and extending onto said tongue portion, said spaced trace portions aligned with and displaced outwardly from a longitudinal axis of the load beam so that a head slider, when mounted on said slider mounting surface of the tongue portion is pivotally movable between the spaced trace portions of the gimbal means, said gimbal means further being aligned with said load beam so that the load protuberance of the load beam will engage the head slider when mounted to said tongue portion.
