Abstract
A method for manufacturing disk drive head suspensions of the type for supporting a transducer head in a loaded state at a fly height above an information storage disk. A desired loaded state side profile for the suspension is determined, for example, by experimental or numerical techniques. The nature and location of one or more weakening structures on the suspension are then determined. The weakening structures will cause the profile of the suspension to change as the suspension moves from an unloaded state to the loaded state, and to have the desired loaded state side profile when in the loaded state at the fly height. Experimental and empirical techniques can be used to determine the nature and location of the weakening structures. A plurality of the suspensions, each having the weakening structures, are then manufactured. Suspension manufactured by the method can be optimized for resonance and other performance-related characteristics.
