    摘要： Provided is an extremely high-density optical recording medium with excellent jitter characteristics and good recording/reproducing characteristics. An optical recording medium 20 comprises a substrate 21 with a guide groove formed therein, a layer 23 with a light reflection function, a recording layer 22 comprising a dye as a main component with a light absorption function for a wavelength of recording/reproducing light in an unrecorded state, and a cover layer 24 capable of transmitting the recording/reproducing light incident to the recording layer 22, in the order mentioned; an interlayer 30 containing at least one element selected from the group consisting of Ta, Nb, V, W, Mo, Cr and Ti, is provided between the layer 23 with the light reflection function and the recording layer 22.
