An information recording apparatus (100, 101, 200, 201, 300, 301) recording information on a recording medium (11) by causing interference of a signal light beam and a reference light beam in said recording medium (11) includes a movable optical deflector (9, 16, 19) deflecting said reference light beam in a direction different from said signal light beam, and a lens (10) collecting said signal light beam and said deflected reference light beam into said recording medium (11) to form interference fringes. |
