Recording heads having an ESD shunt trace and methods of fabricating the
same are disclosed. A recording head of the invention includes a first
shield, a second shield, an MR read element between the first shield and
the second shield, and an ESD shunt trace. The ESD shunt trace is formed
from MR layers and is connected to the MR read element and one or both of
the first shield and the second shield. One or more of the MR layers
forming the ESD shunt trace are processed to reduce the MR properties of
the ESD shunt trace. Examples of processing the ESD shunt trace are ion
milling, ion implantation, oxidizing, reactive ion etching, sputter
etching, wet chemical etching, etc.
