Shingled Writer Design for 10 ${\rm Tb/in}^{2}$ Patterned Media Recording

Abstract

This paper explores the shingled writing head designs for making 10 patterned media data storage more feasible. The relationship between the writing ability improvement of the shingled writing head and the tip width is discussed. The results reveal that a small rounded corner design would be beneficial for improving the writing performance of the writing head. A corner gap, which is slightly smaller than the shield gap, will give the best writing performance.
