Abstract
In this paper we present results of the dynamic response analysis of a rarefied gas lubricated slider bearing on a magnetic recording disk. Although the head slider is subjected to random air lift by disk movement, and there may be some irregularities on the disk surface, it is desired that the head-disk spacing vary periodically even if the acceleration is random, because if not, the head will crash onto the disk surface and magnetic recording memories will break as a result. The object of the present study is to simulate the behavior of the head slider in this case. Various response analyses were conducted on periodic disk movement, but the results of experiment showed that the disk movement is random rather than periodic. To our knowledge, there is no study on treating the response analysis due to random disk vibration. Therefore, it is necessary to conduct a dynamic response analysis on the head slider subjected to random acceleration.
