Optical information recording medium

An optical information recording medium comprising a substrate and a multilayered film formed on the substrate, the multilayered film comprising a first information layer laminate, a separating layer, and a second information layer laminate in this order from a side of the substrate,

• wherein each of the first information layer laminate and the second information layer laminate comprises a recording layer in which an optical change is caused by irradiation of laser light, and in the first and second information layer laminates, signals can be recorded/reproduced on/from the recording layer by irradiating the recording layer with laser light through the substrate,
• the first information layer laminate comprises a first dielectric layer, a second dielectric layer, the recording layer, a third dielectric layer, a fourth dielectric layer in this order from the substrate, the first dielectric layer comprising at least one selected from the group consisting of aluminum nitride, silicon nitride, titanium nitride, silicon carbide and aluminum oxide as a main component, the second dielectric layer comprising at least one selected from the group consisting of zinc sulfide, silicon oxide, and tantalum oxide as a main component, the third dielectric layer comprising at least one selected from the group consisting of zinc sulfide, silicon oxide, and tantalum oxide as a main component, the fourth dielectric layer comprising at least one selected from the group consisting of aluminum nitride, silicon nitride, titanium nitride, silicon carbide and aluminum oxide as a main component.
