A hologram recording method for forming a light interference pattern in a hologram recording medium to record information thereon. The method includes a step of interfering with a reference beam a signal beam spatially modulated by an information pattern which carries the information to generate interfered beams. The method includes a step of executing a recording sequence a plurality of times, the recording sequence including steps of irradiating the interfered beams onto a recording surface of the hologram recording medium to form a group of a plurality of holograms each corresponding to the information pattern. The method includes a step of completing the recording sequence. Different modulation conditions are set for at least one of the signal beam and the reference beam in one recording sequence and the subsequent recording sequence immediately after the one recording sequence.
