Submicron spacing of air-lubricated slider in a disk file with swinging arm actuator

This paper describes the Yaw angle effects on static and dynamic flying characteristics of air-lubricated slider bearings in a disk file with swinging arm actuator. Finite element simulation was carried out to study the static characteristics. It became clear that the slider minimum spacing decreased markedly by yaw angle effect and the results were in good agreement with the experimental investigation. Dynamic characteristics were discussed theoretically from the view point of the slider frequency response to disk vibration and it was found that little difference existed in slider dynamic stability in regard to yaw effect, even when there was a yaw angle of up to 15° in a practical design.
