A three-dimensional finite element analysis method was used to investigate the thermal response of the giant magnetoresistance (GMR) read head excessive current/voltage during an electrostatic discharge (ESD) event. The temperature in the GMR was found to increase sharply with the reduction in the GMR dimensions. It was found that the thermal properties of the GMR elements and the gap materials are important for the accurate prediction of the temperature filed in a GMR head during ESD events. The results show that the perpendicular-to-plane configurations, can sustain high ESD voltages.
