Suspension, head gimbal assembly with multilayered plate suspension having ribs and disk drive apparatus with head gimbal assembly

摘要

A suspension includes a multilayered plate member formed by at least three layers laminated together. The modulus of elasticity of neighboring layers of the at least three layers are different from each other. Both side edges of only a part of the layers of the multilayered plate member within a stiffness-required region are bent to form ribs.
