A disk drive suspension has a mount plate, an outwardly tapered load beam supported by the mount plate and having a base portion, a hinge portion, a beam portion having a first face with turned edges and a flexure supported by the beam portion distally of said beam portion face, and a generally congruent tapered stiffener having a central portion of a given height that is concave and open to the beam portion. The stiffener has left and right flange portions extending laterally from the central portion to the beam portion upturned edges to locate said central portion centrally on the beam portion face.

We claim: 1. A disk drive suspension comprising a beam portion having upturned edge rails at a first face and a flexure supported by said beam portion distally of said edge rails, and a stiffener having a single concave portion of a given height open to said first face and left and right flange portions of respective given widths flanking said single concave portion, the stiffener attached in fixed relation to said first face such that said single concave portion is spaced from said edge rails by said flange given widths. 2. The disk drive suspension according to claim 1 in which said beam portion first face is tapered toward said flexure, said concave portion being generally congruent with said first face. 3. The disk drive suspension according to claim 1, in which said edge rails extend continuously along more than half of said beam portion, and said flange portions have outward facing lateral edges, said lateral edges substantially abutting said upturned edge rails. 4. The disk drive suspension according to claim 1, in which said concave portion has a height dimension between said flanges and the top of said concave portion, and each said flange portion has a width dimension between said concave portion and an outward facing lateral edge of said portion, said concave height dimension being less than each said flange width dimension. 5. The disk drive suspension according to claim 1, in which said beam portion face has a beam portion aperture defining an alignment feature, said stiffener concave portion having a concave portion aperture defining a cooperating alignment feature for registering said stiffener with said beam portion face. 6. The disk drive suspension according to claim 3, in which said concave portion has a height dimension between said flanges and the top of said concave portion, and each said flange portion has a width dimension between said concave portion and said outward facing lateral edge of said flange portion, said concave height dimension being less than each said flange width dimension. 7. The disk drive suspension according to claim 6, in which said beam portion face has a beam portion aperture defining an alignment feature, said stiffener concave portion having a concave portion aperture defining a cooperating alignment feature for registering said stiffener with said beam portion face. 8. The disk drive suspension according to claim 7, in which said beam portion first face is tapered toward said flexure, said concave portion being generally congruent with said first face. 9. The disk drive suspension according to claim 3, in which said lateral edges of said flange portions are disposed less than the thickness of said edge rails away from said edge rails. 10. The disk drive suspension according to claim 3, in which said lateral edges of said flange portions contact said edge rails. 11. A disk drive suspension comprising a mount plate, a hinge portion, an outwardly tapered load beam portion supported by said hinge portion, said beam portion having a first face with upturned edges, the upturned edges extending continuously along more than half of said load beam portion, and a flexure supported by said beam portion distally of said first face, and a generally congruent tapered stiffener, said stiffener attached to said load beam in fixed relation thereto, said stiffener having a central portion of a given height concave and open to said first face, said stiffener having left and right flange portions extending laterally from said central portion to said upturned edges to locate said central portion centrally on said first face. 12. The disk drive suspension according to claim 11, in which said flange portions have outward facing lateral edges, said lateral edges substantially abutting said face turned edges. 13. The disk drive suspension according to claim 12, in which said central portion has a height dimension between said flanges and the top of said central portion, and each said flange portion has a width dimension between said central portion and an outward facing lateral edge of said flange portion, said central portion height dimension being not more than either flange width dimension. 14. The disk drive suspension according to claim 13, in which said beam portion face and said central portion have cooperating aligning structures for registering said stiffener with said beam portion face. 15. The disk drive suspension of claim 11, wherein said left and right flange portions extend to within less than half a width of said upturned edges. 16. The disk drive suspension of claim 11, wherein said left and right flange portions of said stiffener contact said upturned edges in order to centrally locate said stiffener on said load beam. 17. A method of stiffening a load beam, including juxtaposing with a beam portion of a load beam having edge rails a generally congruent stiffener having a concave central portion open to said beam portion and flanges extending laterally outward from said central portion and having lateral edges, centrally locating said stiffener central portion on said beam portion by juxtaposing said flange lateral edges in abutment with said edge rails, and attaching said stiffener to said beam portion in fixed relation therewith.
