An optical recording medium includes a substrate 11 with a concave and convex shape for dividing a track area formed on its surface, an optical recording layer 12 having 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 layer 13 formed on this optical recording layer 12. Then, a compound composition Sn<SUB>x</SUB>N<SUB>y</SUB>O<SUB>z </SUB>of tin (Sn) nitrogen (N) and oxygen (O) comprising the optical recording layer 12 is 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. |
