Abstract

The domain configurations on the air-bearing surface (ABS) of inductive thin-film recording were studied. It was found that, instead of being a single domain structure, the ABS of a thin-film head usually has multidomains. The direction of the domain walls is neither parallel nor perpendicular to the pp plane. The magnetization was found to be in the plane of the ABS along the track width, with the magnetizations onthe two sides of the domain walls either ''head-to-head'' or ''tail-to-tail. '' The domain walls are slanted in order to spread the magneticcharges along the wall over a larger region, thereby reducing magnetostatic energy in this configuration. The responses of the domain wallsare not all in phase, and they are generally out of phase with the rotational process along the gap edge. The magnetization configuration on the ABS and in the throat and the sloped region were investigated inone head and correlated with the domain walls on the ABS.
