Abstract
An optical information recording mediumcomprises a plurality of recording layers, and intermediate layerseach provided between the recording layers. Each of the recording layersincludes polymer binder and dye dispersed in the polymer binder, and the dye is subject to multi-photon absorption of a recording beam RB having a predetermined wavelength and to linear absorption not smaller than 1.5% per recording layer at the predetermined wavelength of the recording beam. When the dye is irradiated with the recording beam and generates heat by linear absorption and multi-photon absorption of the recoding beam RB, the polymer binder undergoes a change of shape by the generated heat, whereby an interface between the recording layerand the intermediate layer undergoes a change of shape to record information.
