Direct arcing to a MR head occurs when the electric field exceeds the dielectric strength of the insulating material. This usually occurs on the air-bearing surface. It can not be prevented by shunting, insulating, or grounding the leads. The most effective solution is to reduce the field strength near the MR head. Two examples from Headway manufacturing… CONTINUE READING
