Application of Magnetic Force Microscopy in Magnetic Recording
With the recent developments of scanning probe microscopes (SPMs), there has been a growth of knowledge about the surfaces of magnetic recording devices. The topography of various mass storage media has been examined in terms of roughness as well as identifying features of the surface. Magnetic track widths and bit widths have been observed and measured showing the differences in resolution as a function of lift height of the magnetic probe. The gap width, surface smoothness and other features of magnetic recording heads have been measured.
The exploding growth of the capabilities of scanning probe microscopes are making these instruments increasingly valuable in research, development, and manufacture of magnetic recording products.
