Abstract: In this thesis, we have investigated three different tilted magnetic recording techniques to extend the capacities of conventional longitudinal recording and conventional perpendicular recording respectively. First technique we have studied is using tilted media to replace longitudinal media in the conventional longitudinal recording system. Using this approach, much higher Ku material has been found feasible with proper recording configurations. Then, we have proposed another recording technique with tilted media and a keepered single-pole head. Under this recording configuration, significant improvements in terms of magnetic properties, signal-to-noise ratio, highest possible Ku, and areal density, have been achieved compared to conventional perpendicular recording. For the above two techniques, it has also been found that a slight in-plane orientation ratio is enough to achieve sufficient performance. Finally, a tilted head field technique has been proposed as an alternative of tilted media technique with a keepered single-pole head. Similar performance advantages over conventional perpendicular recording have been achieved.
