Abstract
A flex suspension assembly is attachable to an actuator arm in a disk drive and includes a suspension assembly adapted to resiliently support a transducer head in the disk drive, and a flex cable having a flexible sleeve and conductors disposed in top of the flexible sleeve adapted to provide a path for electrical signals transmitted to and from the transducer head. A dampening adhesive is applied between the flex cable and the suspension assembly in a dampening adhesive area defined by dampening adhesive control features that bound continuous contact between the flex cable and the suspension assembly. The dampening adhesive has a low modulus of elasticity to provide structural dampening to the flex suspension assembly. In one embodiment, the dampening adhesive provides structural dampening to the flex suspension assembly to significantly reduce first torsion and second torsion vibration mode gains of the flex suspension assembly.
