Effect Of Various Magnetic Structures On Extendibility Of The Longitudinal Thin Film Media Performance to High Recording Density

As we continue to increase the areal density, magnetic recording media having high H

and low media noise are required. In recent years, the flying height has been dropped aggressively to near contact recording in order to extend the life of the inductive head in absence of large volume of MR heads. In this paper, we compare the performance of current oriented and isotropic media and discuss the extendibility of these media to future high density-low flying height applications.
