An entrapped particle in the slider air bearings causes various damages on the surface of slider or the disk, the study of particle movement and adhesion mechanism on the slider surface is critical to reduce the contamination. In this paper, it investigates the interaction between the particles and slider surface. The particle trajectories in the far-field region are calculated using the classical Runge-Kutta method. In the near-field region where the distance between the particle and slider surface less than mesh size (about 1 μm), a novel model for particle velocity and adhesion criterion was proposed to judge whether the particle will be rebounded or captured subsequent to collision on the slider surface. Then the particle trajectory and velocity in the near-field region were presented.
