An optical information recording medium comprises recording layers which include a polymer binder and a dye dispersed in the polymer binder or include a polymer to which a dye is bonded, and each recording layer has a refractive index unchangeable under irradiation with a recording beam, with first and second interfaces being defined between the recording layer and two intermediate layers adjacent thereto. Irradiation of a region of the recording layer adjacent to the first interface or a region of the recording layer adjacent to the second interface with the recording beam causes the dye to absorb the recording beam and generate heat which in turn deforms the polymer in the recording layer, forming a protrusive shape protruding into an intermediate layer at the first or second interface whereby information is recordable in separate information layers at both of the first and the second interfaces.
An optical information recording medium comprising a plurality of recording layers and intermediate layers provided between the plurality of recording layers, which intermediate layers are made of adhesive layers,
A recording method for an optical information recording medium, comprising the steps of:
