Paper Abstract

We have developed magnetic force scanning tunneling microscopy as a powerful tool to analyze magnetic patterns on recording media with sub-micron resolution. The technique employs the interaction of surface magnetic fields with a flexible thin-film magnetic probe. We have made a thorough theoretical analysis of the interaction between the probe and the surface magnetic fields emanating from a typical recorded pattern. Quantitative data about the constituent magnetic fields and the underlying magnetization patterns can then be obtained. We have employed these techniques in studies of two of the most important issues of magnetic recording: data-density and data overwrite. In the course of these studies we have developed new techniques to analyze the magnetic fields of recorded media. These studies are both theoretical and experimental and combined with the use of our magnetic force scanning tunneling microscope should lead to further breakthroughs in the field of magnetic recording.
