Abstract
An optical data recording medium includes a light transmittable plastic substrate, and a recording layer formed on the plastic substrate and containing an inorganic compound body and metal particles dispersed in the inorganic compound body. The inorganic compound body is made from a material selected from a group consisting of a metal oxide and a metal nitride.
Claims9
An optical data recording medium, comprising:
- a light transmittable plastic substrate;
- and
- a recording layer formed on said plastic substrate and containing an inorganic compound body and metal particles dispersed in said inorganic compound body, said inorganic compound body being made from a material selected from a group consisting of a metal oxide and a metal nitride,
- wherein said recording layer contains 5 to 50 atomic percent oxygen when said inorganic compound is made from said metal oxide, and contains 5 to 50 atomic percent nitrogen when said inorganic compound is made from said metal nitride, and
- wherein said recording layer provides said optical data recording medium with a reflectivity greater than 40% in response to a wavelength in a range of from 300 to 900 nm.
