Abstract:
A disk drive suspension adjusted for enhanced resonance performance including a load beam having a distal end, an actuator arm mounting region on a proximal end, a rigid region, a spring region between the rigid region and actuator arm mounting region, and a head mounting region on a distal end of the load beam for receiving a transducer head, the load beam having one or more mass balancing structures in a first configuration between the actuator arm mounting region and the head mounting region, the disk drive suspension comprising:the one or more mass balancing structures being adjusted to a second configuration in response to a measurement representative of a resonance characteristic of the suspension to controllably adjust the mass distribution of the load beam and the resonance characteristic to a desired value wherein the one or more mass balancing structures include mass balancing structures adjacent to a second torsion node location between the actuator arm mounting region and distal end of the load beam.
