Abstract: An optical recording medium in which Sn is used for the recording material a nd the jitter is improved. The medium comprises a substrate (11) having projections/recesses for dividing a track area on its surface. Over the area where the projections/recess are formed, at least a first protective layer (31) for protecting an optical recording layer, an optical recording layer (12) formed on the first protective layer and containing a compound of tin (Sn), nitrogen (N), and oxygen (O), a second protective layer (32) formed on the optical recording layer and protecting the optical recording layer, and a light transmitting layer (13) formed on the second protective layer. The fir st and second protective layers (31, 32) serve to stabilize the optical recordi ng layer (12) at high temperatures and at high humidities.
