ABSTRACT:
An optical recording medium includes a substrate11with a concave and convex shape for dividing a track area formed on its surface, an optical recording layer12having a compound consisting of at least tin (Sn), nitrogen (N) and oxygen (O) formed on the surface in which the concave and convex shape is formed and a light transmission layer13formed on this optical recording layer12.Then, a compound composition SnxNyOzof tin (Sn) nitrogen (N) and oxygen (O) comprising the optical recording layer12is selected so as to satisfy 30<x<70 (atomic %), 1<y<20 (atomic %) and 20<z<60 (atomic %).According to this arrangement, the optical recording medium can improve jitter caused when Sn is used as a recording material.
