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.

Abstract: PURPOSE: An optical recording medium having a super-resolution structure for improvement of reproduction stability and low band noise characteristic are provided to prevent degradation of reproduction characteristic resulting from the diffusion of gas which forms a bubble recording mark. CONSTITUTION: An optical recording medium having a super-resolution structure comprises a plurality of layers formed on the top of a substrate, including a recorded layer(308) and a super-resolution layer(318). The recorded layer contains a material whose decomposition temperature is higher than regeneration temperature and does not form a bubble recording mark in recording. The super-resolution layer is composed of chalcogenide semiconductor material containing one or more selected from nitrogen(N), oxygen(O), carbon(C) and boron(B).
