Abstract:
1. A process to manufacture a synthetically pinned CPP SV magnetic read head, comprising: providing a substrate and depositing thereon a seed and then depositing a layer of antiferromagnetic material on said seed layer; on said layer of antiferromagnetic material, depositing a first layer of an inverse GMR material; depositing a first layer of chromium on said first layer; on said first layer of chromium, depositing a second layer, of cobalt-iron; then depositing a copper spacer layer on said second layer; on said copper spacer layer, depositing a third layer, of low coercivity ferromagnetic material; on said third layer, depositing a second layer of chromium; on said second layer of chromium, depositing a fourth layer, of low coercivity inverse GMR material; and then depositing a cap layer on said fourth layer.
