Claims
- 1. A disk drive suspension comprising a wire bundle, a load beam having a wire bundle attachment locus and supporting along its length said wire bundle, and a head gimbal assembly comprising a flexure and a slider electrically connected to said wire bundle, said load beam being adapted to support said head gimbal assembly, said wire bundle comprising oppositely twisted first and second separable pairs of wires twisted together about each other along a common axis, said load beam having a groove lying along the load beam longitudinal axis, said groove defining said wire bundle attachment locus in which pitch bias from said wire bundle is minimized.
- 2. The disk drive suspension according to claim 1, in which said load beam groove is greater in depth than said wire bundle to protect said wire bundle.
- 3. The disk drive suspension according to claim 1, in which each of said first and second twisted-together wire pairs is separately passed about said flexure.
- 4. A disk drive suspension comprising a load beam having a wire bundle attachment locust, a wire bundle supported along the load beam length at said wire bundle attachment locus, and a head gimbal assembly comprising a flexure and a slider electrically connected to said wire bundle, said wire bundle comprising oppositely twisted first and second separable pairs of wires twisted together about each other along a common axis against inducing roll bias in said wire bundle, said load beam having a longitudinal, axially disposed groove defining said wire bundle attachment locus.
- 5. The disk drive suspension according to claim 4, in which said wire bundle is bonded in said load beam groove.
- 6. The disk drive suspension according to claim 5, in which said load beam groove is sized to bodily receive said wire bundle entirely within said groove.
- 7. The disk drive suspension according to claim 6, in which said flexure has left and right lateral portions, said first and second twisted together wire pairs being separated from each other beyond said groove and each separated pair routed laterally of said left or right flexure lateral portions.
