In order to meet the requirements of the near-field optical storage system for higher density

higher communication speed and integration

a subminiature anti-particles load-supporting stage was designed for low wear and high near-field coupling efficiency. A model of air bearing surface was investigated and solved using the finite volume method for analysis of the flying characteristics. The abundant negative pressure sufficiently enhances the stiffness and stability of the stage. The wedge-shaped rails and the novel distribution of negative force efficiently reduce the particles. The rail etched on the SIL achieved ultra sub-micron displacement from the disk surface. The theoretical analysis and computation show that a near-field gap of less than 50 nm can be successfully obtained. The carrying capacity exceeds 88 mN. Few particles are retained under the SIL. The flying head is robust for the near-field optical system.
