Abstract :
A new method of calculating the medium field for shielded MR and GMR heads was developed. The new method is accurate, quick to execute, and compact. Unlike the finite element method it requires no special mesh making process. These features make the new method, when combined with a micromagnetic simulation for MR film magnetization, a useful tool for the head design. The present method can also be used in various problems, such as the self demagnetizing field calculation for MR films
