Abstract

A new method that significantly improves signal contrast when using solid immersion lens (SIL) optics with a certain phase-change recording layer structure is proposed. Linearly polarized light is used to illuminate the lens that focuses light onto the medium, and a special filter is used to block negative signal components from reaching the detector after light is reflected from the recording layers. Numerical calculation showed that the minimum contrast can be improved from near zero to over 0.25 by the filtering.
