    摘要: An optical data storage system includes an optical disc which stores information in optically readable format on a data surface. A slider is provided proximate the data surface of the optical disc and is coupled to an actuator for selectively positioning the slider relative to the data surface. A Solid Immersion Lens couples to the slider and is arranged to couple light to the data surface of the optical disc. The Solid Immersion Lens is non-hemispherical.
