A critical review of existing head-disk interface modeling capabilities is given. Modeling of two important technologies, miniaturization of current air-bearing devices and viscoelastic bearings, e.g., VISqUS technology, is studied in a unified manner. New developments are: (i) the Fokker-Planck equation is adopted for rarefaction effects (instead of Boltzmann equation) in air-bearing technology; and (ii) systematic studies on incompressible liquid bearings are performed.>
