Optical recording disc and method of the production thereof
摘要:
An optical recording disc comprises a resin layer of resin material formed on a relatively rough surface of each of transparent disc substrates, the resin material having approximately the same refractive index of light as the refractive index of the transparent disc substrate, and a recording layer formed on each of said resin layers. Accordingly, the optical recording disc enables to decrease the production cost and to write and read an information signal into and from the recording layer at an improved signal to noise ratio than a conventional optical recording disc.
