Optical recording medium and method of manufacturing thereof |
摘要 |
The object of the present invention is to provide a an optical recording medium provided with a reflective film having a high reflectivity and durability and a means for producing thereof, and it can be obtained by a method comprising the steps of: first placing on a heating object an aluminum metal alloy containing at least one of 0.05-0.2 wt.% metal selected from the group of iron, copper and silicon, and also having 0.7-3.0 wt.% manganese; and evaporating the aluminum metal alloy in a vacuum by means of a vapor deposition process to an information signal recorded surface of a transparent synthetic resin plate. In other words, an optical recording medium according to the present invention is provided with a light reflective film covering an information signal recorded surface of a transparent synthetic resin plate, wherein the light reflective film is formed in a vacuum by means of a vapor deposition process of an aluminum metal alloy containing at least one of 0.05-0.2 wt.% metal selected from a group of iron, copper and silicon, and also containing 0.7-3.0 wt.% manganese.
