This specification discloses a recording apparatus using coherent light which comprises coherent light generating means for generating coherent light, light modulating means into which the coherent light from the coherent light generating means enters, whereby when in ON state, the light modulating means emits the entering coherent light outwardly as zero-order light having a certain angle of emergence and when in OFF state, the light modulating means derives the entering coherent light as a primary light having another angle of emergence, the primary light being intercepted by an intercepting member so as not to be emitted outwardly, means for applying modulating signal to the light modulating means for controlling ON-OFF of the light modulating means, deflector means for deflecting the zero-order light emitted from the light modulating means, and a recording medium upon which the deflected zero-order light is thrown and which is sensitized by the zero-order light from the light modulating means when in ON state and which is not sensitized by the zero-order light leaking from the light modulating means when in OFF state.
