An optimization method for magnetic disk drive suspensions that improves resonant frequencies in the access direction is described. The basic principles of this method are widening the node portions and narrowing the loop portions of a suspension in the sway mode. The frequency response characteristics were predicted with an precision analysis, which included deformation of the loaded suspension. These methods were applied to an integrated head suspension system, named pico-CAPS. We confirmed that the resonant frequency of the sway mode was higher than 10 kHz, with an increase of 20%, and also confirmed the validity of these methods
