Abstract
The contact of regular patterned rough surface in magnetic recording was analyzed to predict the contact area, meniscus force and permissible load under thin-film lubricated conditions. The contact area, the meniscus force, and the permissible load at the magnetic head-disk interface were studied as a function of the shape, size and the occupation of asperities. Optimum design criteria for both constant occupation and nonconstant occupation of identical asperities were developed to design future magnetic head and disk surfaces.
