ABSTRACT:
A process for reducing deformation of a holder arm, which holds a head of a data recording device, includes cutting a metal body to form the holder arm and contouring a tip of the holder arm by wire cutting. The step of contouring preferably includes steps of placing a voltage between the metal body and a wire, moving the wire, and bringing the wire adjacent the metal body to contour the tip of the holder arm.
