Patent ID: 7365944

Claim:
A magnetic head suspension comprising: a flexure portion which has a magnetic head mount area for supporting a magnetic head slider; a load bend portion which generates a load for pressing said magnetic head slider to a storage surface of a storage medium; a load beam portion which transmits said load to said magnetic head mount area; and a base portion which supports said load bend portion, wherein said load beam portion includes: a base end area which is continuously connected with said load bend portion, an intermediate area which extends from the base end area toward a tip end side, and a tip end area which extends from the intermediate area toward the tip end side and reaches said magnetic head mount area, said tip end area being formed with an opening through which a jig is inserted for electrically connecting a wiring structure supported by the flexure portion to a terminal of said magnetic head slider by a gold ball bonding, said base end area has a pair of first side edges tilted so as to gradually approach a central longitudinal axis line of the magnetic bead suspension as said pair of first side edges go toward the tip end side, said intermediate area has a pair of second side edges continuously connected with said pair of first side edges, respectively and configured so as to be substantially parallel with said central longitudinal axis line or to be tilted to gradually approach the central longitudinal axis line as said pair of second side edges go toward the tip end side, said tip end area has a pair of third side edges extending toward the tip end side from said pair of second side edges, respectively, said pair of first side edges have a larger tilt angle with respect to said central longitudinal axis line in comparison with said pair of second side edges, said pair of third side edges are gradually spaced apart from the central longitudinal axis line as said pair of third side edges go toward the tip end side so as to be capable of enlarging a width of the opening through which the jig is inserted, said load beam portion has reinforcement structures formed by a pair of flanges arranged at both sides of said load beam portion, the pair of flanges extending so as to be over a pair of first inflection points where said pair of first side edges respectively intersect with said pair of second side edges, in respect to a central longitudinal axial direction, and to be over a pair of second inflection points where said pair of second side edges respectively intersect with said pair of third side edges, in respect to the central longitudinal axial direction.
