ABSTRACT:
A system for reading or writing data from or to a bilevel optical recording medium with a flying head. The system includes a head having a slider and a solid immersion lens mounted at least partially within the slider. The solid immersion lens has a partial spherical surface and a substantially flat surface. The head also has an objective lens mounted to the slider. The system also includes a multilevel recording medium. The medium has a first media layer and a first substrate layer adjacent to the first media layer. The medium also has at least one second media layer adjacent the side of the first substrate layer opposite from the first media layer, and a second substrate layer adjacent the side of the second media layer opposite from the first substrate layer. The total effective numerical aperture of the system is greater than one for all layers.
