ABSTRACT:
A disk drive suspension component for carrying a slider at a disk is formed of a laminate of at least three metal layers of like mechanical and chemical formability, including a first outer layer, a second outer layer, and an intermediate layer, at least one of the layers having a void-containing interior and a surface area having an undivided series of local regions distributed across substantially the width and length thereof with each local region equaling less than 10% of the surface area. Each of the local regions have an overall pattern of discontinuities and lands between the discontinuities substantially the same as the overall pattern of discontinuities and lands in laterally and longitudinally adjacent local regions for local attachment of the layers at some and not all of the lands to adjacent layers to form a laminate having common formability properties, high rigidity and light weight.
