Gimbal assembly resonance mode anti-biasing

摘要

A data storage system includes an actuator assembly including a load beam having a base plate end and a slider end. A bias feature is formed in the load beam near the base plate end of the load beam. The bias feature is configured to induce lateral motion on the load beam when the slider end is displaced along a z-axis. An anti-bias feature is positioned between the bias feature and the slider end of the load beam. The anti-bias feature is configured to induce lateral motion on the load beam during resonance of the load beam to oppose the lateral motion induced by the bias feature.

1. A load beam having a proximate end and a distal end, the load beam comprising:
a bias feature near the proximate end of the load beam, the bias feature inducing lateral motion on the load beam on the load beam when the distal end is displaced along a z-axis; and an anti-bias feature positioned between the bias feature and the distal end of the load beam, the anti-bias feature inducing lateral motion in the load beam during resonance of the load beam, the anti-bias-feature-induced lateral motion opposing the lateral motion induced by the bias feature.
