Disclosed is an optical recording medium comprising a transparent substrate having a tracking line formed therein, and a recording layer formed on that surface of the substrate in which is formed the tracking line. The recording layer consists of a low oxide of nickel. Also disclosed is an optical recording medium comprising a transparent substrate consisting of a thermoplastic resin, a thermosetting resin layer formed on each surface of the substrate, a patterned photoresist layer, said patterned photoresist layer being formed on one of the thermosetting resin layer, and a recording layer formed to cover the exposed portion of the thermosetting resin layer and the patterned photoresist layer.
