A head suspension for supporting a read/write head in a dynamic rigid disk data storage device and applying a load force on the read/write head in a load direction when the storage device is in operation, the suspension comprising an elongated loadbeam portion extending along a longitudinal axis having a bending spring rate in the load direction. The loadbeam comprises a rigid mounting portion at a proximal end of the loadbeam portion for attaching the loadbeam portion to an actuating mechanism, a rigid load portion at a distal end of the loadbeam portion for supporting an assembly configured to carry the read/write head, and a spring portion integrally formed with the mounting region and load region and having partially etched regions with a thickness that is smaller than the mounting region and load region. The spring portion appreciably affects the bending spring rate. The boundary between the spring portion and mounting portion comprises at least a first segment that is not perpendicular to the longitudinal axis. The boundary between the spring portion and load portion comprises at least a second segment that is not perpendicular to the longitudinal axis.
