Abstract
A disk drive suspension in which resonance characteristics are adjustable and a method for such adjustment. The disk drive suspension includes a load beam, a head mounting region and one or more mass balancing structures. The mass balancing structures are adapted for permanent displacement or removal to adjust mass distribution of the load beam. In this way, resonance characteristics of the load beam can be adjusted. A method of adjustment includes determination of an adjust location on the load beam at which a resonance characteristic to be adjusted is sensitive to changes in mass. The mass distribution of the load beam are adjusted at this adjust location.
