| 主权项 | 1. A method of forming a magneto-resistive reader comprising: depositing a first shield element, the first shield element comprising two ferromagnetic anisotropic layers separated by a grain growth suppression layer; annealing the first shield element at a magnetic set anneal temperature to form a set annealed first shield; depositing a magneto-resistive sensor stack on the annealed first shield; annealing the magneto-resistive sensor stack at a magnetic cross set anneal temperature to form a cross set annealed magneto-resistive sensor stack; and depositing a second shield element on the cross set annealed magneto-resistive sensor stack. | ||
