A stiffener mounted on a disk drive motor limits bending to improve stroke efficiency and resonance performance.
A stacked d33 mode PZT microactuator uses a stiff constraint layer to increase effective stroke length.
Integrating deformable arm portions into the microactuator mounting section prevents deformation during handling while maintaining sway-direction accuracy.
Integrally formed stainless steel PZT limiters constrain vertical displacement of microactuator piezoelectric elements in dual stage suspensions.
