摘要： Laser light emitted from a laser light source is irradiated onto a transmission-type scale, and is diffracted by a polarization hologram recorded on the transmission-type scale. Only polarization directions of ±1-order diffracted lights, among diffracted lights, are rotated by 90°. The ±1-order diffracted lights interfere with one another such that interference fringes are formed on a light-receiving surface of a photo-detector. Interference light of the ±1-order diffracted lights is transmitted through a polarizing plate. A portion of transmitted light is passed through respective slits of a slit plate and is irradiated onto the photo-detector, and intensity of irradiated light is detected. On the other hand, 0-order diffracted light, ±2-order diffracted lights, and the like, whose polarization directions are not rotated, cannot pass through the polarizing plate, and are blocked before being detected at the photo-detector.

The invention provides an optical recording medium enabling large scale recording by making the photosensitive layer thick without impairing recording characteristics. The photo-responsive high-molecular compound preferably comprises an aromatic ring on a main chain. Further, the photo-responsive high-molecular compound preferably comprises a structural unit which is capable of forming a liquid-crystalline or crystalline polymer and a structural unit which is capable of forming an amorphous polymer.
