A method of making a base plate blank by either photo-etching or laser-cutting a blank. The base plate blank includes at least two radial troughs symmetrically arranged about a swage center. The base plate blank is used to make a base plate for a head gimbal assembly by die-stamping the base plate blank, which for at least one of the radial troughs, forms a contact zone away from the radial trough. The die-stamping further includes forming a contact zone away from the radial trough, for each of the radial troughs. The head suspension assembly including the base plate, a head gimbal assembly including the head suspension assembly, an actuator assembly including at least one head gimbal assembly, and a hard disk drive including the actuator assembly, as well as the methods of making the elements of the invention, and those elements as products of these methods.
