Disc drive suspension including load beam having different cross-sectional shapes at welded and non-welded parts thereof

A disc drive suspension with a load beam and a flexure, wherein the load beam comprises:

• a load beam main body;
• welding parts by which the flexure and the load beam main body are fixed to each other;
• a pair of flange bending parts formed at respective sides of the load beam main body, the flange bending parts including first bending parts extending in a length direction of the load beam main body, and the flange bending parts bending in a first direction along a thickness direction of the load beam main body;
• a second bending part formed between the flange bending parts, the second bending part extending in a width direction of the load beam main body, and the second bending part bending in the first direction;
• a first cross-section part extending in the width direction through the welding parts, the first cross-section part being warped up in a second direction toward the flange bending parts;
• and
• a non-welded second cross-section part extending in the width direction along the second bending part through a position different from a position of the welding parts, the non-welded second cross-section part not passing through the welding parts or any other welding part,
• wherein warping up in the second direction of the non-welded second cross-section part in a vicinity of the flange bending parts is suppressed during formation of the second bending part, whereby the non-welded second cross-section part has a lesser height difference and a flatter shape as compared to the first cross-section part.
