Abstract :
ESD robustness was studied for GMR heads with CrMnPt anti ferro material. We also studied the magnetic instability of GMR heads with dual GMR structure. It was found that heads with thick film structure had good ESD robustness and that the heads with dual structure had good stability by ESD.
