An optical information recording medium includes a substrate formed in a
concave-convex state by providing pits or grooves corresponding to
recorded information, used for optically reproducing the information by
irradiation of a light beam, and may also include a recording layer. The
optical information recording medium includes a temperature responsive
layer 21 whose reflectance and/or transmittance for the light beam
changes with an increase in temperature caused by the irradiation of a
light beam and a light absorption layer 22. With such an arrangement, the
present invention provides an optical information recording medium
enabling secure and highly accurate readout of information recorded with
high density, a recording method and a readout method using the same, a
readout device, and a recording device.
