A high-speed, write-once type optical recording medium, which utilizes laser light that is either blue or an even shorter wavelength, as well as an optical recording method and an optical recording apparatus for recording onto this optical recording medium.A high-speed, write-once type optical recording medium 10 having a recording layer 18 and a light transmission layer 22 formed sequentially on top of a support substrate 12, wherein the recording layer 18 is formed by laminating first and second vice-recording layers 18A, 18B which include Al and Sb respectively as primary components, and irradiation of a laser light of blue wavelength from a laser light source 24, through the light transmission layer 22 and onto the recording layer 18, causes diffusion and mixing of the Al and Sb contained within the first and second vice-recording layers 18A, 18B, and this mixing enables the formation of a recording mark based on an irreversible change in reflectance. The thickness of the recording layer 18 is set to enable recording at a recording transfer rate of at least 35 Mbps.
