Abstract

Recently, the near field recording using a Solid Immersion Lens (SIL) is getting much attention to be a promising candidate of super high density optical recording. The high density recording is achieved by introducing a highindex SIL between the recording medium and the objective lens, thereby increasing the numerical aperture (NA) of the optical system and reducing the focal spot size. The SIL lens is usually a hemisphere or a super-hemisphere. The preliminary analyses of readout signal in this case have been reported.
