A recording apparatus includes a plurality of Xenon flash tubes and a separate enclosure for each of said flash tubes. Each enclosure is provided with a slit through which light from the associated flash tube emerges to form a relatively small line segment. The slits are all located in a recording plane and may be disposed in an H-shaped or C-shaped recording array, as desired. When placed in cooperative relation with a moving light sensitive recording medium that is ultrasensitive to a predominant wavelength of the light produced by said flash tubes, selective and appropriate flashing of said flash tubes produces dense analog time code and other traces on said recording medium.
