Abstract
In a disk drive suspension, a gimbal is longitudinally moment-balanced about the dimple to improve shock performance by adding weight to one side of the gimbal and/or by removing weight from the other side of the gimbal, such that when the suspension experiences an operational shock the gimbal the gimbal tends to stay level with the disk surface and not pitch relative to the disk surface. The gimbal may be moment balanced by leaving or depositing on the suspension's limiter tab the same insulative material as is used to form the flexible circuit, by increasing the mass of the limiter tab, and/or by reducing the size of the detabs or the trailing edge, or by other means.
