ABSTRACT:
An electro-optical storage system based on an air-bearing-suspended optical head and operated in a near-field configuration. The system comprises a read/write head and a head positioning system, an optics module including beam relay optics and signal detectors, an optical medium and a corresponding medium driving unit, and an electronic control system. The optical head includes a near-field lens positioned over the optical medium by a fraction of the wavelength. A transition dielectric layer is formed on the near-field lens to improve the optical and mechanical coupling between the head and the optical medium.
