ABSTRACT:
A low friction non-gaussian surface is disclosed which has a positive skewness value and a kurtosis value of three or greater which minimizes static and kinetic friction and resultant wear. In a preferred embodiment, a magnetic storage media having an optimal non-gaussian surface roughness and method of surface parameter selection utilizes non-gaussian probability density functions in a contact model which accounts for the effects of roughness distribution and liquid film meniscus forces to determine optimum skewness and kurtosis values which minimize static and kinetic friction. The invention provides a magnetic storage media with a surface which has a positive skewness value and as high a kurtosis value as possible which minimizes static and kinetic friction at the disk/head interface and minimizes wear of the magnetic storage device.
