An optical recording medium using Sn as the recording material to improve
the jitter is provided, in which on the surface of a disc substrate 11
where a concave and convex shape dividing a track area is formed, are
formed on the surface of the concave and convex shape a first protective
layer 31 for protecting at least an optical recording layer 31, an
optical recording layer 12 using a chemical compound at least composed of
tin (Sn), nitrogen (N) and oxygen (O), formed on the first protective
layer, a second protective layer 32 for protecting this optical recording
layer, formed on this optical recording layer, and a light-transmittable
layer 13 formed on the second protective layer; with this structure, the
optical recording layer 12 under high temperature and high humidity can
be stabilized by means of the first and second protective layers 31 and
32.
