ABSTRACT:
A head suspension including a load beam and flexure having a vibration absorbing member for vibrating at resonance mode vibrations of the head suspension. The load beam includes a mounting region at a proximal end, a rigid region adjacent to a distal end, and a spring region between the mounting region and the rigid region. The flexure is at the distal end of the load beam and is for supporting a head slider. The vibration absorbing member extends from the head suspension and has a resonance mode frequency substantially the same as one of the resonance mode frequencies of the head suspension. As such, the vibration absorbing member absorbs energy on the head suspension at a resonance mode frequency thereof, acting to reduce gain at a resonance mode frequency of the head suspension.
