Abstract: A flexure chain blank sheet includes frame units. Each frame unit includes a frame portion, and flexure elements. The flexure element includes a distal end portion, and an extending portion. The frame portion includes a pair of lengthwise frames and a pair of lateral frames. The first lateral frame connects between tail portions of the flexure elements. The second lateral frame is formed of a distal end linking portion which is constituted by connecting between respective adjacent extending portions. The distal end linking portion includes first cut-off portions to be cut along a longitudinal direction between the adjacent extending portions, and second cut-off portions to be cut along a width direction between the distal end portion and the extending portion.

Abstract: A disk drive suspension of the embodiments includes a load beam, and a flexure including a mounting portion on which a slider is mounted and overlapping with the load beam. The load beam includes a tab further extending than the mounting portion longitudinal direction of the load beam. The tab is shaped in an arc such that a central portion in a lateral direction protrudes with respect to both end portions in the lateral direction, in the load beam. Each of the both end portions includes a flat surface parallel to the lateral direction.

Abstract: A flexure chain blank sheet includes a plurality of frame units. Each of the frame units includes a frame portion, and a plurality of flexure elements arranged within the frame portion. The frame portion includes lengthwise frames extending in a longitudinal direction of the flexure elements, and lateral frames extending in a width direction of the flexure elements. A slit that extends along the lateral frames, a connection portion, and recesses are formed between adjacent frame units. An opening width of the recesses is greater than an opening width of the slit. The connection portion includes a portion-to-be-cut which is to be cut by a cutter. The recesses allow insertion of the cutter.
