Abstract

A head suspension assembly for positioning a head assembly at the correct static attitude with respect to the surface of a rotatable data storage device. The head assembly includes a gimbal assembly having a novel static attitude adjustment feature comprising a solid drop of material. The solid drop of material is dispensed as a fluid on the desired location and then cured to solid form. The solidified drop of material can be used to create surface features on head suspension assemblies for correcting pitch and roll static attitude errors and for applying gram loads on the head assembly.
