摘要：

The feasibility of discrete track media with perpendicular anisotropy for high track density is studied. The discrete tracks are separated physically and magnetically by the grooves. The actual media was fabricated to evaluate the basic write/read properties. The measurements have been done with a spin stand. As a result, discrete track media showed a better write efficiency and recorded signal separation between the adjacent tracks compared to the conventional continuous recording layer media. It indicates the potential of this media for high track density recording.
