An optical recording head comprises a cathode for emitting electrons, and an emission element array, provided apart from the cathode. The emission element array has a substrate, a plurality of anodes arranged at predetermined intervals on the substrate, a plurality of phosphor cells, arranged in contact to the anodes on the substrate, for emitting light based on the electrons from the cathode, and an insulation layer formed on the substrate, and a control electrode, laid out on the insulation layer while being electrically insulated from the anodes, in such a way as to surround the phosphor cells. The control electrode accelerates the electrons from the cathode.
