To obtain an optical recording medium capable of recording at various recording transfer rates from a low speed to a high speed, by using a simple recording strategy.A recording layer 18 of a write-once optical recording medium capable of recording from a low speed to a high speed is formed by laminating a first sub recording layer 18A and a second sub recording layer 18B each containing a metal as its main component. When the recording layer (laminated recording layer) 18 is irradiated with a laser beam having a wavelength equal to or shorter than a blue wavelength by using a recording strategy comprising only a ratio of write power to bias power, the main component metals contained in the first and second sub recording layers 18A, 18B diffuse and are thus mixed together, forming the sub recording layers into a single layer by means of such mixing and forming recording marks whose reflectance have been irreversibly changed. Since the recording mark formation process does not need to select a recording strategy, it is possible to obtain many subordinate advantages such as a variable speed recording.
