An optical information recording apparatus, an optical information reproducing apparatus, and an optical information storing medium are provided to record optical information in the optical information storing medium and simultaneously record servo information in the optical information storing medium. A light source(101) emits one beam. The first and the second beam splitters(110,120) divide the beam into an information beam, a servo beam, and a reference beam. An SLM(Spatial Light Modulator)(130) loads data in the information beam. The information beam is inputted to an optical information storing area. The servo beam is inputted to a servo information storing area. The reference beam is simultaneously inputted to the optical information storing area and the servo information storing area. An interference pattern by the information beam and the reference beam is recorded in the optical information storing area. An interference pattern by the servo beam and the reference beam is recorded in the servo information storing area.
