The present invention relates to a method for producing an optical recording medium. In the method, on the surface of a recording layer formed by spin-coating a first coating solution containing a photo-isomerizable component, a second coating solution that contains a photo-isomerizable component that can be isomerized by radiation having the same wavelength as radiation used for isomerizing the photo-isomerizable component contained in the recording layer and incapable of dissolving the recording layer is spin-coated to form an intermediate layer. Since the intermediate layer thus formed cannot be dissolved by the first coating solution, a recording layer is further laminated on this layer. Thus, it becomes possible to make the recording layer thicker and also to provide a high-density recording characteristic.

Optical recording medium and method for producing such an optical recording medium

An image-forming device which is equipped with an image-holding member, an exposure section provided with plural light-emitting portions arranged in a first direction, a movement section that relatively moves the exposure section and the image-holding member in a second direction that intersects with the first direction, and a light-emission control section. The light-emission control section causes the plural light-emitting portions to periodically emit light in accordance with image data representing an image that is to be formed on the image-holding member, to form the image on the image-holding member. The light-emission control section varies a light-emission period during formation of the image, so as to correct for periodic fluctuations within the image of at least one of density and magnification ratio in the second direction.

A multifunction system has advanced functions and high speed capability and is excellent in expandability. The multifunction system includes a controller, an IIT, an IOT, and a light distributing device. For a print job, print data outputted from the controller is converted into optical signals, which enter a light distributing device and are transmitted to the IOT of the emission side. The IOT prints the received data onto a printer. For a copy job, copy data outputted from IIT is converted into optical signals, which enter the light distributing device, and are transmitted to the IOT of the emission side. For a scan job, scan data outputted from the scanner is converted into optical signals, which enter the light distributing device, and are transmitted to the controller of the emission side. The controller processes the received data.

Multifunction system

An optical recording/reproducing apparatus having excellent resistance against vibration and noise. In recording, coherent light is polarization-modulated with a spatial light modulator to generate signal light and reference light whose polarization directions are crossed at right angles. The signal light permeates a polarizing beam splitter, and is incident to a quarter wavelength plate. The reference light passes through a passing hole, is diffused by a light diffuser and is incident to the quarter wavelength plate. The reference and signal light are converted into circularly polarized light which revolve in directions opposite to each other and condensed by a condenser lens, and then a predetermined area of an optical recording medium is irradiated with the reference and signal light. Thus, the reference and signal light are generated by modulating the incident light from the same light source and are coaxially incident to the polarizing beam splitter.
