Abstract
An optical data recording medium includes a light transmittable plastic substrate, and a recording layer formed on the plastic substrate and containing a hydrogenated amorphous material that is selected from a group consisting of hydrogenated amorphous carbon, hydrogenated amorphous silicon carbide, hydrogenated amorphous boron carbide, hydrogenated amorphous boron nitride, hydrogenated amorphous silicon, and hydrogenated amorphous germanium.
Claims14
An optical data recording medium, comprising:
- a light transmittable plastic substrate;
- and
- a recording layer formed on said plastic substrate and containing a hydrogenated amorphous material that is selected from a group consisting of hydrogenated amorphous carbon, hydrogenated amorphous silicon carbide, hydrogenated amorphous boron carbide, hydrogenated amorphous boron nitride, hydrogenated amorphous silicon, and hydrogenated amorphous germanium.
An optical data recording medium, comprising:
- a light transmittable plastic substrate;
- and
- a recording layer formed on said plastic substrate and made from hydrogenated amorphous carbon which contains 5 to 60 atomic percent hydrogen and which decomposes and releases hydrogen at a temperature greater than 300° C., said plastic substrate being softened at a temperature in a range of from 80° C. to 300° C. so as to permit formation of recesses in said plastic substrate as a result of the hydrogen released by said hydrogenated amorphous carbon.
