Abstract

Electro static discharge (ESD) sensitivity and thermal stability of Spin Valve (SV) heads with pinned synthetic ferrimagnet (SynPin) were studied by using quasistatic tester (QST) in HGA level. Compared with conventional SV (CSV) head, SynPin SV showed better ESD endurance and thermal stability which comes from stronger pinning field at high temperature (>300°C). Based on this paper, it is expected that SynPin SV has advantages in the SV heads fabrication process in ESD tolerance and also has more advantages in thermal reliability of SV.
