Magnetoresistive sensor design for signal noise pickup reduction for use with deep gap electrostatic discharge shunt

摘要

A magnetic head having an electrostatic shunt structure for preventing damage to the magnetic head during manufacture. A portion of the shunt structure is removed during manufacture, however another portion remains. In order to prevent the remaining portions of the shunt structure from picking up stray magnetic and electromagnetic fields, an electromagnetic shield, is provided between the remaining portions of the shunt structure and the substrate.
