ABSTRACT:
A head gimbal measurer for measuring the force loading on a head, the head having a plurality of air bearing surfaces, to predict the fly height of a selected one of the plurality of air bearing surfaces when the head is in operation relative to a rotating magnetically coated disc, including a measurement device for measuring the total normal force on the head and the differential normal force on each air bearing surface. A comparing device for comparing the measured total normal force on the head and the differential normal force on each air bearing surface with a known total normal force on the head and a known differential normal force on each air bearing surface to predict a fly height of the head when in operation relative to the rotating magnetically coated disc. The invention is further a load distribution measurement and adjustment device designed to shape a load arm of a head gimbal assembly used to transfer data to and from a rotating magnetically coated disc.
