Abstract:
According to one embodiment, an optical recording medium is provided in which interlayer crosstalk is low and in which stable and high-quality recording characteristics can be obtained. To this end, in this optical recording medium, an intermediate layer whose thickness variation is managed to be equal to or less than a predetermined value is provided between a first recording part and a second recording part.
