1. An optical system for recording information on the surface of a light sensitive medium comprising:

  • a two-dimentional array of laser diodes mounted on a curved substrate and arranged in such a way to converge laser beams of said laser diodes onto an intermediate lens, each laser diode having a separate collimating lens in optical alignment therewith, said collimating lens collecting most of the emitted light from said laser diode;

    a lens for imaging said array of laser diodes onto said light sensitive surface;

    one or more intermediate lenses placed between said imaging lens and said array of laser diodes in order to reduce the image size, and a means for adjusting the position of each laser diode relative to said collimating lens to deliver a substantial amount of the emitted light from each laser diode to the surface of said medium.
