Abstract
A method to test an instability of a magneto-resistive (MR) head. The instability is tested by first writing a signal onto a track. The junctions of the MR head are aligned with various track edges and the head characteristics are then measured. The characteristics may include determining a maximum amplitude covarian and a maximum base line popping noise.
