More Information
Summary:The present invention generally relates to a magnetic recording system that utilizes perpendicular exchange spring media and ring heads. The write field of ring heads does not experience a strong loss as compared to pole heads because the pole can be kept long in the direction perpendicular to the recording medium and thus does not result in unfavorable write field scaling.
