The shield is in a down track direction from the first read sensor and between the first and second read sensors. The shield includes a first shield layer, a second shield layer and an insulating layer between the first and second shield layers. The first shield layer is between the first read sensor and the second shield layer. The second shield layer is between the first shield layer and the second read sensor. The first shield layer has a first footprint. The second shield layer has a second footprint. The second shield layer overlaps the first shield layer in the down track direction. The overlap is not more than fifty percent of the first footprint and not more than fifty percent of the second footprint.
