Abstract
Embodiments of the present invention help to increase yaw stiffness while achieving higher peel stiffness and lower roll stiffness and pitch stiffness in a suspension supporting a head slider. A gimbal according to an aspect of the present invention has a securing point where the gimbal is secured to a load beam in the front and securing points where the gimbal is secured to the load beam in the rear. The gimbal tongue pivots on a dimple contact point. A front ring is secured at the securing point to support the gimbal tongue. The rear ring is secured at the securing points to support the gimbal tongue. The rear ring provides the gimbal tongue with higher yaw stiffness than the front ring. The front ring provides the gimbal tongue with higher peel stiffness than the rear ring.
