Evaluation of wrist strap monitors from an MR head perspective

Abstract

Magnetoresistive (MR) heads are very sensitive devices that can be damaged by applying a current that exceeds the normal bias current of the head, which is typically around 10 mA for anisotropic magnetoresistive (AMR) devices. Contact with the head from a charged object can cause damaging current transients. Depending on the magnitude of the charge, these… (More)
