摘要： 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.

摘要： Disclosed is a high-quality archival optical recording medium which enables to obtain good recording/reproducing characteristics in high-speed recording and high-density recording. Specifically disclosed is an optical recording medium comprising a resin substrate, a recording layer containing an organic dye and a reflective layer. This optical recording medium is characterized in that 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 lower thermal conductivity than the first reflective layer, and the first reflective layer is thicker than the second reflective layer.
