Abstract :
The write field of multilayered integrated heads has been computed avoiding the usual assumptions that the head contour is an equipotential surface, by starting from the effect of the coil field on the magnetization of the layers. The magnetic analysis assumes that the magnetization of each layer curls near the head boundary, and it is shown that this curling significantly affects the write-field distribution. Experimental measurements are in good agreement with these theoretical results, and it is shown that integrated heads produce a write field whose magnitude is comparable to that of classical heads.
