Method for determining the quality of a lubricant layer on a magnetic recording medium by detecting electrons at varying drawing angles

摘要

The quality of a lubricant layer formed on a surface of a magnetic recording medium is determined by exposing the lubricant molecules of the lubricant layer to a radiation source for x-ray photoelectron spectroscopy while varying the photoelectron drawing angle. The number of emitted electrons is determined and, from this, the degree of orientation and the quality of the lubricant layer is found.
