Dynamics of air bearing slider with nano-meter level proximity contact

This paper presents a comprehensive study on the vibrations of slider with pseudo contact air bearing surface designs on sliding disk. It is found that the shift between contact and loss-of-contact results in the large non-linearity of the system. A typical interface with proximity recording slider is numerically investigated and the theoretical model is simplified to derive a comprehensive closed-form solution. Finally, it is illustrated that these derived results agree qualitatively well with existing experiments.
