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

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 of the backing layer.
