The magneto optical disc is provided with at least first and second recording layers such that the record information is recorded to the first recording layer at a vertically magnetized state thereof and is also recorded to the second recording layer at a vertically magnetized state thereof. The information recording method of recording record information to the magneto optical disc is provided with the steps of: controlling an output power of a recording light; irradiating the recording light to the record position; and applying, while irradiating the recording light to the magneto optical disc, to the record position, an external magnetic field.
