A method and system for providing a dual spin valve is disclosed. The dual spin valve is for reading data in a magnetic recording media. The method and system include providing a first pinned layer. The first pinned layer has a first magnetization. The method and system also include providing a CoFe free layer and providing a first nonmagnetic spacer layer. The first nonmagnetic spacer layer is between the first pinned layer and the CoFe free layer. The method and system also include providing a second pinned layer and a second nonmagnetic spacer layer. The second pinned layer has a second magnetization. The second nonmagnetic spacer layer is between the CoFe free layer and the second pinned layer.
A dual spin valve for reading data in a magnetic recording media, the dual spin valve comprising:
A method for providing dual spin valve comprising the steps of:
The method 13 wherein the first pinning layer further includes a first antiferromagnetic pinning layer and wherein the second pinning layer further includes a second antiferromagnetic pinning layer.
The method 13 wherein the first pinning layer further includes a first synthetic antiferromagnetic pinning layer and wherein the second pinning layer further includes a second synthetic antiferromagnetic pinning layer.
