Abstract |
Demand of higher areal density in HDD, several Tb/in^2, bring about technology transfer of magnetic read heads: CIP-GMR, CPP-TMR and CPP-GMR. This work for the first time presents the comparison of the resilience of all three reader technologies to Electrostatic Discharge (ESD) event on both hard failure and soft failure at the same time. The threshold ESD current causing both failures was determined by using by Finite Element Simulation. Critical parameters such as Blocking Temperature (TB), Neel Temperature (TN), Curie Temperature (TC), and Electric Field Breakdown (EB) while an ESD current being applied to a particular heads were monitored. The results conclude the high resilience of reader technologies to ESD is listed in order as CPP-GMR, CIP-GMR and CPP-TMR. Moreover, the percentage threshold ESD current of hard and soft failures of CIP-GMR and CPP-TMR comparing with that of CPP-GMR are (a) Hard Failure: 67.10% and 1.29% (b) Soft Failure: 99.49% and 6.12% |
