     Abstract This work presents the tolerance of TMR and CPP-GMR heads to ESD events when the sizes of both reader technologies are shrinking. The shrinking size effect actually indicates the growth of AD targeting to Tb/in2. Blocking temperature, melting temperature, and electric field breakdown of the oxide layer are the key parameters for investigation upon the temperature increment of TMR and CPP-GMR heads caused by ESD current. The investigation was carried out by using a finite element analysis, solver and simulation software. The results reveal that at 30% shrinking size, TMR is 15% less tolerance to ESD phenomena than CPP-GMR technology for the case of hard failure. On the other hand, CPP-GMR is approximately 10% more sensitive to ESD event than TMR technology for the case of soft failure case.
