To provide an optical recording method, optical recording apparatus and optical recording medium, capable of effective control of light irradiation position, such as focusing control or tracking control, at the time of recording or reproducing and efficiently adjusting the light irradiation position control according to variations in distance between layers in an optical recording medium or according to manufacturing errors in optical recording and reproducing apparatus, the method including applying at least one of an information light and a reference light to an optical recording medium for detection and control of focus positions of the information light and reference light in a thickness direction of the optical recording medium; and applying the information light and reference light to form an interference image to be recorded in a recording layer provided in the optical recording medium, wherein information is recorded in the recording layer by holography.
