In order to make clear the dynamic adhesion force of a slider in near contact regime, we experimentally investigated the dynamic collision motion of a spherical slider on a magnetic disk. We used the spherical glass slider with 0.5, 1, 2mm radius and the magnetic disks with different lubricant thickness of 0, 1, 2 and 3nm with and without UV treatment. As a result, we found that the dynamic adhesion force of 1mm radius slider is slightly larger than the static meniscus force (4πRγ), while that of 2mm radius slider is slightly smaller than the static meniscus force, probably because of insufficient formation of meniscus bridge. We also found that contact force is estimated by Hertzian contact theory.
