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.
