A recording apparatus includes a pulse oscillation laser (11), a half mirror (12) for splitting the pulse oscillation light of the laser into a signal light (2) and a reference light (3), an optical shutter (13) disposed in the optical path of the signal light, a beam expander (14) for converting the signal light into a light beam of a predetermined diameter, a spatial modulator (15) for modulating the recording data into two-dimensional image information, a Fourier Transform lens (16) for introducing the signal light modulated by the spatial modulator onto a recording medium (1), mirrors (17, 18) for introducing the reference light onto the recording medium with a predetermined angle, a system control unit (21), a laser driver (22), a system controller (23), a recording medium drive mechanism (24), a modulator driver (25), a data input unit (26a), and a data processing unit (27).
