    摘要: An optical information recording apparatus includes a first optical system that radiates an information beam that carries information onto a recording medium; a second optical system that radiates reference beams onto the recording medium; a radiation position specifying unit that specifies a plurality of recording spots positioned within a radiation range of the reference beams; and an incident angle obtaining unit that specifies an incident angle of the reference beams that is used for recording an i'th interference fringe into a second recording spot adjacent to a first recording spot, as a value obtained by adding a product of 1/(1+m) and an absolute value of a difference between an incident angle of a first reference beam used for recording an i'th interference fringe into the first recording spot and an incident angle of a second reference beam used for recording an (i+1)'th interference fringe into the first recording spot.
