Estimating the term…
An optical information recording medium comprising a substrate, and a dielectric layer, a recording layer, a dielectric layer and a reflective layer which are laminated on the substrate in this order or a reflective layer, a dielectric layer, a recording layer and a dielectric layer which are laminated on the substrate in this order, wherein a state of the recording layer is reversibly changed between optically recognizable states by irradiation of, for example, a laser beam and the recording layer has a thickness of from 1 nm to 10 nm, which recording medium has improved recording sensitivity.
