ABSTRACT:
This invention provides a high-output magnetic head with a high yield, which is capable of minimizing sense current leak or noise caused by a shift of the magnetic wall of an upper shield layer. In one embodiment, the magnetic head is fabricated so that the height of the upper surface of the refill film along the sensor height direction is the same as that of the magnetoresistance layer in a portion where the refill film along the sensor height direction comes in contact with the magnetoresistance layer and the distance from the upper surface of the refill film along the sensor height direction to the upper surface of the lower shield layer gradually increases in a region from the portion where the refill film along the sensor height direction comes in contact with the magnetoresistance layer to a point at a certain distance away from the portion.
