To achieve the ever smaller slider-disk spacing that is required for the continual increase in data storage density of hard disk drives, it is necessary to understand the interaction between the slider and the lubricant layer. As the lubricant layer has been used in the hard drive industry for many years, the general properties of the lubricant have been well-studied. However, a focus in the literature has been on theoretical and simulation-based studies. This dissertation focuses on experimental studies of the behavior of the lubricant occurring in the slider-disk interface while the slider is flying. General experimental observations seen across many experimental studies are given. Experimental investigations on the influence of various experimental parameters on the lubricant modulation are detailed. The recovery of the lubricant after the experiment has stopped is explored. A unique experimental observation of droplets of lubricant suddenly appearing in the slider-disk interface is detailed. Finally, studies on how the latest hard-drive technology, thermal fly-height control (TFC), changes the slider-lubricant interactions as compared to traditional slider designs are given
