Abstract :
A method is described for obtaining all three components of the field produced by a magnetic recording head. The perpendicular component of the field, Hy, is measured in the plane of the air-bearing surface, and from this the three components, Hx, Hy, and Hz , are calculated in the region below the surface. An example is presented of the field distribution for a thin-film head, and a comparison is made with both analytic and three-dimensional finite-element calculations
