Abstract
In a suspension in a hard disk drive, a gimbal with asymmetric dynamic properties, in which the two halves of the gimbal may have different stiffness distribution or inertia distribution. Structural difference between the two halves, or materials with different stiffness, may cause the different stiffness distribution or inertia distribution. When the suspension vibrates, the different stiffness and/or inertia distribution increase the friction between the gimbal and a load beam of the suspension, and increase the damping of the suspension.
