摘要:
Optically readable information disc having a glass sub-- strate plate (1) and a recording layer (3) in which on the side of the recording layer the surface of the substrate plate is provided with a transparent layer (2) of a material which impedes the diffusion of Na and/or K from the substrate plate to the recording layer or in which the said surface is provided with a transparent layer of a cross-linked synthetic resin on which the layer of the diffusion-impeding material is provided.
