Zusammenfassung:Write-to-read coupling in HGAs has been studied. We report on the relative contribution of the coupling from the suspension interconnect and the slider. By implementing different measurement setups, we have demonstrated both suspension interconnect and slider have a profound contribution. The induced read current not only adversely affects read sensor stability, but can cause reader degradation as well.
