The present invention provides a recording medium that has high reliability and affords good recording and reproduction characteristics over a wide linear velocity range and high density, as well as a method for manufacturing the recording medium. To this end, an optical information recording medium comprises at least a recording layer that changes its state to be different and optically detectable by irradiating with a light beam, an optical absorption layer composed of a material containing at least 50 at % and no more than 95 at % silicon, and a reflective layer composed of a material containing at least 95 at % silver and no more than 5 at % indium, with these layers provided in that order on a transparent substrate. |
