Impacts of windowed backing layer on write-to-read coupling on suspension interconnection

Abstract

The effect of backing layer windowing on write-to-read coupling based on s-parameter analysis by using 3D simulation tool is studied. The two different windowed structure patterns of TSA interconnection are compared to observe the transmission coefficient of write-to-read coupling. From simulation results, it is found that the windowed structure in the middle of the backing layer shows smaller transmission coefficient than that at lateral ofthe backing layer.
