Abstract
A suspension for supporting a transducer in a data storage system includes a longitudinal axis, a proximal mounting section, and first and second opposing side edges. The suspension includes a rigid load beam section that extends longitudinally along the longitudinal axis. A flexible section is located between the proximal mounting section and the rigid load beam section. The flexible section has a preload bend transverse the longitudinal axis and a peak strain region located between the preload bend and the rigid load beam section. A damper covers a portion of the peak strain region.
Claims19
A suspension comprising:
- a longitudinal axis;
- a first side edge and a second side edge, the first and second side edges located on opposite sides of the longitudinal axis;
- a proximal mounting section;
- a rigid load beam section, wherein the first and second side edges in the rigid load beam section are positioned at a first angle with respect to the longitudinal axis;
- a flexible section located between the proximal mounting section and the rigid load beam section and having a preload bend, wherein the first and second side edges are at least partially positioned in the flexible section at a second angle with respect to the longitudinal axis, wherein the first and second angles are different;
- a peak strain region located between the preload bend and the rigid load beam section, wherein the peak strain region is located at least partially on the longitudinal axis;
- and
- a damper covering at least a portion of the peak strain region.
