Abstract
A recordable optical disk including a transparent substrate; a recording layer formed over the substrate; a reflective layer formed over the recording layer; and a thin metallic interlayer formed on the recording layer at the interface between the reflective layer and the recording layer wherein the thin metal interlayer includes materials selected from the group consisting of Pd, Ni, Sn, Au, In, Te, Si, Ge, and alloys thereof, the interlayer being selected so as to improve the optical disk recording stability without significantly affecting the reflection of a recording light beam passing through the substrate and the recording layer and which is reflected by the reflective layer.
