Optical information recording medium and method for optical recording, reproducing and erasing information |
摘要 |
Disclosed is an optical information recording medium which has: a rigid substrate; recording film for recording information that is optically detected by laser light, the recording film being formed on the rigid substrate or concave-convex pits for recording information that is optically detected, the concave-convex pits being formed on the rigid substrate; and a transparent thin plate and the recording film being pasted together by a transparent adhesive layer. Also disclosed is a method for optically recording, reproducing and erasing information which has the step of: providing an optical information recording medium in which a recording member that is physically or chemically changed by the incidence of laser light is formed on a rigid substrate; wherein the recording, reproducing and erasing of information is conducted through the recording member by laser light which incides on the rigid substrate through a transparent thin plate formed on the rigid substrate. <IMAGE> |
