Analysis of Contact Deformation and Stiction Between Textured Disk and Textured Slider

To meet the ever-increasing magnetic recording density, the hard disk industry is focusing on reducing flying height. Texturing the slider surface to reduce the head–disk contact area is one of the most challenging and promising techniques in the current industry. In this study, a mathematical–physical model based on an extension of the Greenwood–Tripp model is proposed for predicting and analyzing the contact deformation and stiction between both textured disk and slider. The contact deformation and stiction of the head–disk interface is analyzed in considering surface texture parameters, lubricant properties, and loading conditions.
