Abstract

In one embodiment, a variably conductive shunt is provided for protecting a read/write sensor element, e.g., an MR read element, which has first and second terminals. A variably conductive member is electrically connected between the first and second terminals. The variably conductive member conducts charge when a potential sufficient to damage the element is applied across the first and second terminals thereby protecting the element from the charge.
