Abstract: A thin film head includes a permeable substrate providing a first shield, which may include a more highly permeable layer on its upper surface for shielding, a layer of permeable material thereon providing a second shield and a first write head leg referred to as the shielding-leg layer and a magnetic gap filled with dielectric material between the substrate and the shielding-leg layer. A magnetoresistive stripe including permeable material extends within the dielectric in said gap near the tip end of the head spaced from the substrate and the shielding-leg layer. An inductive single turn or multiturn writing winding is formed upon a layer of dielectric on the other side of the shielding-leg layer. A second leg layer covers the half of the spiral winding towards the tip end of the head and extends through an opening into contact with the shielding-leg layer.
