Abstract
A head supporting apparatus comprises an arm driven by a positioning motor of a disk drive and a suspension adhered to a suspension attachment portion of the arm via a base plate. The suspension includes a load beam, a head, and so on. A coarse surface is provided on a surface of the base plate which is brought into contact with the adhesive. The coarse surface has a function of rendering adhesion of the adhesive to the base plate greater than adhesion of the adhesive to the arm. The coarse surface is obtained by forming a number of minute cavities on the base plate by a press process.
