In a dual stage actuated (DSA) suspension, a PZT microactuator is electrically and mechanically bonded to the rest of the suspension by non-conductive epoxy on the front and rear bottom faces of the PZT, by conductive epoxy that bridges a gap between the top face of the PZT which defines the ground electrode and an adjacent metallic and grounded portion of the suspension, and further by additional non-conductive epoxy that bridges the gap and which at least partly overlies the conductive epoxy. The additional non-conductive epoxy increases the effective stroke length of the PZT.

Method and apparatus in which a disk drive suspension flexure tongue supports a slider. A flexure frame attached to a suspension supports the tongue in dimple engagement with the suspension. Spaced, separate biasing structures on the frame act oppositely on the tongue for a net increase in tongue dimple contact force.

Static attitude (SA) adjustment of a disk drive suspension load beam is conducted before final alignment of a limiter to increase adjustment range, to avoid limiter damage, and to minimize unintended distortion of parts during adjustment. To have the SA adjustment before final alignment of the suspension, the limiter is carried by the load beam beam portion in first position in which the limiter is out of operative association with the flexure tongue during static attitude adjustment. The limiter is shifted into operative association with the tongue only following the static attitude adjustment, typically in a plane being generally parallel with the tongue plane.
