Patent ID: 8136227

Claim:
A method for making a magnetic head having non-GMR shunt for perpendicular recording, comprising: forming a read head including a magnetic reading sensor disposed between a first and second shield; depositing over only a portion of the magnetic reading sensor a photoresist layer having a shape selected for exposing a portion of the magnetic reading sensor to form a shunt within the magnetic reading sensor and between the first and second shield to prevent charge buildup between the first and second shield; removing the portion of the magnetic reading sensor exposed by the photoresist layer to form a void in the magnetic reading sensor directly behind a portion of the magnetic reading sensor and between side portions of the magnetic reading sensor to produce the shape selected for forming the shunt; refilling the void with a non-GMR material to form the shunt circumscribing a back and the sides of the magnetic reading sensor; removing the photoresist layer; and forming leads to the magnetic reading sensor.
