Abstract

Design of slider rail for contamination control becomes an important issue in magnetic recording. In this paper, trajectory of particles in a slider disk interface was simulated with considerations on various forces, such as drag force, gravitational force, Saffman lift force, and electrostatic force, all of which affect the motion of the particles. It was found that the charged particles could easily adhere to the slider or the disk surface if an electric field existed in the slider disk interface. It was presumed that the vertical motion of the particles would not only be related to the Saffman force but also to the electrostatic force.
