Method for defining a magnetoresistive junction using multiple mills at a plurality of angles
A method and system define a magnetoresistive junction in a magnetic recording transducer. The method and system include performing a first mill at a first angle from a normal to the surface of the magnetic recording transducer. A second mill is performed at a second angle from the normal to the surface. The second angle is larger than the first angle. A third mill is performed at a third angle from the normal to the surface. The third angle is not larger than the first angle.
