英文摘要	A series of nanoscratch experiments is conducted using constant loading scratch profiles to apply mechanical contact stress on perpendicular magnetic recording (PMR) media to cause its magnetic signal strength decay, which is characterized by the magnetic force microscope. The dependence of the magnetic signal strength on the applied normal load is quantitatively investigated. The results indicate that an increase of the applied normal load leads to a decrease of the magnetic signal strength. In addition, in order to obtain a more complete understanding of the results, a 3D finite element model is created to calculate the stress under different normal loads. Finally, the quantitative relationship between residual shear stress and magnetic signal strength is identified. (C) 2014 AIP Publishing LLC.
