Process for producing optical recording medium. |
摘要 |
<p>An optical recording medium is produced through a process including the steps of forming an optical recording layer (9) comprising an organic film on a substrate (1) and irradiating the organic film with laser light (10) 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.</p> |
