Abstract
A TMR-compensating suspension, or one or more suspension components such as a hinge or beam that can be assembled with other components to make a suspension. The suspension includes a proximal actuator mounting region, a rigid beam region, and a spring region or spring legs between the actuator mounting and beam regions. The load beam or component is formed from a multi-layer laminate and is configured with an offset structure at the spring region or spring legs that skews or twists the beam region with respect to the actuator mounting region. Motion of the beam region with respect to the actuator mounting region when the load beam is used in a disk drive will therefore include a TMR-compensating radial component.
Claims2
A hinge component for use with a load beam and manufactured from a laminate including first and second spring metal layers separated by an etch stop layer, the hinge component having a spring region including a TMR-compensating offset structure and non-coplanar spring legs, comprising:
- a first spring leg formed from only the first spring metal layer and optionally the etch stop layer, and
- a second spring leg formed from the first spring metal layer, the second spring metal layer and the etch stop layer, the first spring leg having a gap in the first spring metal layer.
