Abstract
A flex cable assembly for a head stack assembly of a hard disk drive comprises a flex cable for conducting data signals from the head stack assembly to a connector. The flex cable has a dynamic loop section between a termination for the head stack assembly and the connector. The flex cable has a constrained layer damper for attenuating random transient vibration. The constrained layer damper has a symmetrically tapered shape for reducing stress concentration and is coupled with the dynamic loop section of the flex cable adjacent to an area of the flex cable configured for receiving a coupler for coupling the flex cable assembly with the head stack assembly.
