Abstract:
A method for developing and manufacturing a head suspension of the type having a load beam, a mounting region on a proximal end of the load beam, a flexure on a distal end of the load beam, a rigid region and a spring region between the rigid region and the mounting region, and which has at least a rigid region side profile optimized for one or more selected resonance char method including:providing a flat model of the suspension;generating a plurality of profile/resonance characterizing variations of the model, each characterizing variation having a different side profile through at least the rigid region of the suspension;determining, for each selected resonance characteristic, a profile description and resonance characteristic response of each profile/resonance characterizing variation;generating, for each selected resonance characteristic and from the profile description and resonance characteristic response of the profile/resonance characterizing variations, a numeric profile/resonance equation describing the resonance characteristic response of the suspension as a function of the profile;determining an optimum suspension profile description by solving the profile/resonance equations for the desired resonance characteristic response; andmanufacturing one or more suspensions having the determined optimum suspension profile.
