Abstract:
An optical information medium comprising:a substrate or a pair of substrates; at least two information-storing layers configured to store recorded information and/or tracking servo information disposed on said substrate or between said pair of substrates, wherein at least one information-storing layer is recorded or read by a recording beam or a reading beam which has passed through other information-storing layer(s); and at least one resin-containing intermediate layer in contact with each of said information-storing layers, wherein each said at least one resin-containing intermediate layer is formed between the at least two information-storing layers and is a cured intermediate layer comprising an active energy radiation-curable resin, and said at least one cured intermediate layer has a tensile elongation at break of 15 to 200% and a tensile modulus of 20 to 1,000 MPa.
