    摘要： An optical information recording medium including three or more information layers, wherein at least one information layer provided on the light incident side is an information layer which enables information to be overwritten and includes a recording film, a transmittance adjusting film of a dielectric containing Bi, Ti and O, and an isolation film in this order from a light incident side; and the isolation film is provided between and adjacent to the transmittance adjusting film and an intermediate separation layer which separate the information layer from another information layer on the side opposite to the light incident side; and the isolation film has an optical constant at a wavelength of 405 nm such that a refractive index is 1.8 or less and an extinction coefficient is 0.05 or less. This information recording medium prevents the repeated overwriting characteristics in a sever environment from being deteriorated.
