Abstract:
An optical information recording medium includes: a recording layer 12 comprising a multi-photon absorption compound and a one-photon absorption compound; and a supporting member (base layer 11) configured to support the recording layer 12. In this optical information recording medium, absorption of multiple photons by the multi-photon absorption compound and absorption of one photon by the one-photon absorption compound cause a void to be generated in the recording layer, whereby information is recordable by modulation based on a presence or absence of a void.
