Optical recording device

An optical recording device comprises at least one light guide layer, a plurality of light emitting units and a photosensitive medium. The light guide layer comprises a plurality of light transmissionstructures and a plurality of light absorption structures, wherein the plurality of light transmission structures and the plurality of light absorption structures are closely connected and alternately arranged. The plurality of light-emitting units are respectively arranged on the plurality of light-transmitting structures of the light guide layer, and the plurality of light-emitting units are used for emitting light towards the corresponding light-transmitting structures. The photosensitive medium is arranged below the light guide layer and is used for receiving light rays which are emittedby the plurality of light-emitting units and pass through the light guide layer; and therefore, the photosensitive medium receives light with a small divergence angle, and the quality of recorded images and imaging is further
