Abstract
The invention is principally to provide an archival optical recording medium of high quality which has satisfactory recording/reading characteristics when used in high-speed recording and high-density recording. The invention accomplishes the object with an optical recording medium comprising a resin substrate, a recording layer comprising an organic dye, and a reflective layer, wherein the reflective layer has a first reflective layer and a second reflective layer in this order from the side close to the recording layer, the second reflective layer has a thermal conductivity lower than the thermal conductivity of the first reflective layer, and the first reflective layer has a film thickness larger than the thickness of the second reflective layer.
