Abstract:
A super-resolution optical recording medium includes a reflective layer formed on a substrate, a recording layer for recording information thereon, a super-resolution layer made of a chalcogenide semiconductor material, and a first and a second dielectric layers laminated on upper and lower surfaces of the super-resolution layer. The recording layer is made of a material that has a decomposition temperature higher than an information reproduction temperature and does not form bubble recording marks during recording, and the super-resolution layer contains one or more elements selected from the group consisting of nitrogen, oxygen, carbon, and boron.
