Abstract:
In one embodiment, a magnetic sensor comprises a read element and a magnetic-domain-control film positioned on both sides of the read element in a cross-track direction. The magnetic-domain-control film has a flare shape which causes the magnetic-domain-control film to flare away in an element height direction from the depthwise end of read element and extending in both directions away from the read element in a cross-track direction. In another embodiment, a method for forming a magnetic sensor includes forming a read element and forming a magnetic-domain-control film positioned on both sides of the read element in a cross-track direction, wherein the magnetic-domain-control film has a flare shape which causes the magnetic-domain-control film to flare away from the depthwise end of read element extending in both directions in a cross-track direction.
