Apparatus for adjusting the static attitude of a head suspension having a gimbal with at least one gimbal arm. One embodiment of the invention includes a pair of first contacting members contacting a first side of the gimbal arm at a pair of spaced apart locations, and a second contacting member contacting a second side of the gimbal arm at an intermediate location between the spaced apart locations. The first and second contacting members move together relative to each other, plastically deforming the gimbal arm by the relative movement between the second and first contacting members while the spaced apart location between the first contacting members is maintained during the plastic deformation such that at least one of a pitch and roll parameter of the gimbal is adjusted to a desired amount.

Apparatus for adjusting pitch and roll in a head suspension

A disk drive head suspension headlift formed from a single piece of stainless steel includes a beam region, lift tab and offset region between the beam region and lift tab. The beam region has a major surface and formed side rails. The lift tab is a coined, trough-shaped member at a z-height spaced from the major surface of the beam region. The offset region has a major surface and side rails that transition in height between the side rails of the beam region and the lift tab.

Coined headlift with formed rail offset for a disk drive head suspension component

A headlift on a distal end of a load beam of the type for use in a disk drive suspension, including two distally extending rails transversely spaced from each other, a cross member extending between the first and second rails, and a tab extending from the cross member. The headlift may include arms extending transversely from each rail that engage with each other and with an offset formed in the load beam. In one embodiment, the headlift is integrally formed from the same piece of material as the headlift. In a second embodiment, the headlift is formed from a polymer and attached to the load beam. The method of manufacture, in one embodiment, includes providing a unitary flat load beam member and folding the load beam member and attaching portions of the headlift to the load beam to form the headlift. Alternatively, the load beam may be formed with a structural surface that interfaces with a mounting portion of the headlift.

Headlift for disk drive head suspension

Apparatus and method for adjusting at least one of a pitch and roll parameter of a gimbal for a head suspension assembly having a pair of members contacting at least one gimbal arm at spaced apart locations and having an additional member contacting the gimbal arm intermediate the spaced apart locations and wherein the members move together to cause plastic deformation of the gimbal arm. A like apparatus and method may be used sequentially or concurrently on a second gimbal arm, and may have an inverted orientation with respect to the first apparatus.
