<p>Disclosed is an information recording medium comprising a substrate, a first recording layer which is irradiated with a recording laser light through the substrate for recording information, and a second recording layer which is irradiated with the recording laser light through the substrate and the first recording layer for recording information. The first recording layer contains such a material that it has a higher light transmittance than would be the case if it were composed of the same material as the second recording layer.</p>
