Abstract: A dual stage actuated (DSA) suspension includes two PZT microactuators that are attached at their first ends to a non-gimbaled portion of the suspension, and are attached at their second ends to the gimbaled portion of the suspension such as the gimbal tongue through flexible connectors that can be formed integrally with the suspension's flexure. The flexible connectors are flexible enough so as not to interfere with the suspension's gimballing action. The flexible connectors transmit force from the PZTs to the gimbal as the PZTs expand and contract in order to rotate the gimbal and thus effect fine movements of the head slider. The flexible connectors are positioned laterally outwardly of the leading edge of the slider, thereby protecting both the connectors and the PZTs from damage induced by the slider striking the connectors during a shock event.
