Recording apparatus for recording information included in an electro-magnetic radiation-beam applied thereto and recording head used for the same.

摘要

PURPOSE:To improve resolution and to prevent a recording head from dropping its sensitivity in a specific wavelength area by arranging a charge generating layer on a recording layer side, making electromagnetic radiant ray flux incide from the recording layer side and recording information in the recording layer. CONSTITUTION:A recording medium 10 consists of the recording layer 12, a transparent electrode layer 14, a color decomposing filter layer 16, and a glass base layer 18, the recording head 40 consists of a charge generating layer 22a forming a photoconductive layer 22, a charge transporting layer 22b, an electrode layer 24, and a base layer 26 and a layer 22a is arranged on the recording layer side reversly from a conventional method. In said constitution, the optical image of a subject 28 is made incident upon a photographing lens 30 and decomposed to the three primary colors and a charge image corresponding to the optical image is formed on the surface of the layer 22. Since the optical image is made incident upon the layer 22a after being color-decomposed through the layer 12, the resolution is improved and the recording device can be prevented from dropping its sensitivity in the specific wavelength range.
