ABSTRACT:
A novel head stack assembly (HSA), and method for HSA assembly, are disclosed and claimed. A first flexure tail has a long axis approximately parallel to a side of the actuator arm. The actuator arm includes a slot in the side having a slot end. The first flexure tail is disposed partially within the slot. The first flexure tail includes a first raised region in contact with the slot adjacent the slot end. The first raised region includes an out-of-plane bend with cross-sectional curvature along the long axis. The first raised region may be squeezed while inserting the first flexure tail partially within the side slot, with the first raised region adjacent the slot end, and then allowed to expand into contact with the slot adjacent the slot end.
