A thin film magnetoresistive head is provided which has a magnetoresistive thin film sensing element. The film surfaces of the sensing element are bounded by top and bottom surfaces and a pair of side surfaces, the bottom surface forming a portion of an air-bearing surface. First and second sense current thin film lead layers are provided. The first lead layer is electrically connected to the top surface of the magnetoresistive element and the second lead layer is electrically connected to the bottom surface of the magnetoresistive element. First and second gap layers and first and second shield layers are provided. The magnetoresistive element is located between the first and second gap layers. The magnetoresistive element, the lead layers, and the first and second gap layers are located between the first and second shield layers. Provision is made for electrically connecting the second lead layer to the second shield layer and provision is made for electrically connecting the first and second shield layers. With this arrangement, shorting between the layers at the air-bearing surface of the head is overcome. Further, by proper electrical connection of these components to a turntable, electrical shorting between the head, at the air-bearing surface, and the surface of a magnetic disk rotating therebelow is overcome.
