1. An optical information recording device utilizing holography, comprising:

  • a light source;

    a deflection element for changing the traveling direction of light emitted from the light source;

    a means for generating information light holding information using light of which the traveling direction has been changed by the deflection element;

    a means for generating recording reference light using light of which the traveling direction has been changed by the deflection element;

    an objective lens for irradiating information light and recording reference light to the moving recording medium; and

    a control means for controlling the deflection element and enabling the irradiation position of the objective lens to the recording medium to follow the movement of the recording medium.
