Abstract

This article describes a fly height regulator utilizing a bimetallic element providing normal force to head suspension which effects the preloading and regulates gram load as an additional file adjustment. There is always a need to vary the fly height of a head without altering other parameters in files, production testers, diagnostic testers, and in the laboratory. The magnetic head fly height regulator 1 includes a regulator beam 2 with predetermined flexural capability which presses against a head suspension assembly 3 supported on a file arm 4, thereby applying a normal force to the suspension and altering the preload.
