ABSTRACT:
An optical recording medium for optical data recording and reproduction is produced through a process including the steps of forming an optical recording layer comprising an organic film on a substrate and irradiating the organic film with laser light to scatter the irradiated portion of the organic film, thus forming a tracking groove thereat and leaving an optical recording part along the tracking groove. The thus formed optical recording part and tracking groove provide a high reflectivity ratio or a high reflective contrast, whereby a good tracking fidelity is ensured during the optical recording and reproduction.
