Abstract
Method and apparatus for attenuating resonances in a flex circuit which interconnects a stationary element and a moveable element, such as a connector and a head stack assembly (HSA) in a data storage device. An intermediary portion of the flex circuit forms a dynamic loop between the stationary element and the moveable element. A damper member is attached to the flex circuit so as to continuously extend adjacent the stationary element and along less than an overall extent of the dynamic loop. The damper member attenuates resonances excited in the flex circuit during movement of the moveable element.
