Gimbal assembly with contoured gimbal arms for improved gimbal resonance

A head suspension assembly comprising:

• a slider;
• a load beam including a load tab having a load button;
• opposed spaced gimbal arms separated to form a gap having a width wider than the slider, each gimbal arm including a leading edge portion, a trailing edge portion and an intermediate portion, the leading edge portion having a bulbous structure to provide lateral stiffness and the intermediate portion formed of a structure tapered from the leading and trailing edge portions to provide a center portion of reduced mass;
• and
• a dimpleless slider tab operably coupled to the trailing edge portions of the opposed gimbal arms to support the slider in the gap between the opposed gimbal arms wherein the slider includes a SIL supported between a leading edge and a trailing edge of the slider, and located toward the trailing edge, spaced from the leading edge of the slider so that the SIL is off-centered relative to the leading and trailing edges;
• wire termination pads on a portion of the slider between the leading edge and the SIL;
• and the load button aligned with a portion of the slider between the leading edge and the SIL;
• and the slider tab connected to a portion of the slider between the SIL and the trailing edge of the slider.
