Abstract

This invention incorporates a fluorescence microscope for visualizing what the disk lubricant does when a magnetic recording head slider contacts with or flies near a rotating transparent disk covered with a thin film consisting of the lubricant of interest and a small percentage of fluorescence tag soluble in the lubricant. In this invention, high quality fluorescence optical microscope positioned to observe the slider-disk interface through a transparent disk, as the slider flies over the transparent disk.
