Abstract :
The write field of a ring head used with the preferred medium for perpendicular recording (CoCr with an underlayer of softmagnetic material) is discussed and compared with the write field of a Thin- -Film Single Pole (TF-SP) head on the basis of two-dimensional calculations. It is found that the saturation of the underlayer plays an important role in the shape as well as the magnitude of the calculated write field.
