Abstract: An optical disk recording apparatus, an optical disk recording method, an optical disk playback apparatus, and an optical disk playback method are provided. For example, the present invention is applied to a high-sound-quality optical disk (4, 6Z) which can be played back by a conventional compact disk player, and aims at supplying still higher-quality contents which can be played back even by a conventional optical disk apparatus. Second information (SC) is recorded by partial changes of optical characteristics, such changes being of such a degree which does not affect detection results of first and second areas which are detected by the irradiation of a laser beam (L2).

Abstract: A light orientation film and a liquid crystal thin film are formed adjacent to each other. Light is irradiated to the light orientation film and the liquid crystal thin film, so as to cause the light orientation film to be orientated while viscosity of the liquid crystal thin film is lowered by a temperature increase by the light irradiation, so that an intermolecular force on the boundary between the light orientation film and the liquid crystal thin film causes the liquid crystal molecules in the liquid crystal thin film to be orientated according to the orientation of the light orientation film. By this orientation of the liquid crystal molecules, recording information is maintained. Thus, it is possible to realize a sufficient signal amount while using the light orientation film as well as to obtain a thermal stability and a stability against light irradiation.

Abstract: An optical alignment film and a liquid crystal thin film are adjacently formed. These films are irradiated with light. The optical alignment film is aligned, and the viscosity of the liquid crystal thin film is lowered becaus e of the increase of the temperature due to light irradiation. The liquid crystal molecules in the liquid crystal thin film are aligned similarly to t he alignment of the optical alignment film by use of the intermolecular force a t the interface between the optical alignment film and the liquid crystal thin film. The alignment of the liquid crystal molecules allows the recorded information to be held. While using this optical alignment film, a sufficiently large amount of signals are realized, and the thermal stability and the stability against light irradiation are ensured.

Abstract: A three-dimensional object is produced by repeatedly exposing successive layers of liquid photosetting resin at the surface of a quantity of the resin stored in a vessel to a light beam so as to change each light beam exposed layer of the liquid photosetting resin into a solidified layer, stepwise incrementally moving each solidified layer downward into the liquid photosetting resin in the vessel so that a new layer of the liquid photosetting resin is coated on the solidified layer, detecting the temperature of the liquid photosetting resin, and heating the liquid photosetting resin in accordance with the detected temperature to maintain the fluidity of the liquid photosetting resin.

Abstract: A master recording apparatus which comprises a revolving base (31) for revolving a substrate (1) coated with resist thereon, an irradiating mechanism (32), an elevator mechanism (33) for making the irradiating mechanism (32) capable of moving in a vertical direction and in a surface direction which is perpendicular to the vertical direction relative to the revolving base (31) and a height position displacement mechanism (35) interposing between the irradiating mechanism (32) and the elevator mechanism (35). The irradiating mechanism (32) is connected with the elevator mechanism (33) through the height position displacement mechanism (35) and the irradiating mechanism (32) has such a structure in which at least a converging lens system (36) and a displacement driving mechanism (37) for adjusting a focus are supported by a gas static pressure pad housing (38). In the gas static pressure pad housing (38) a gas feeding pad (39) is disposed facing a bottom surface opposing the substrate and gas (such as air) is made to be fed between the irradiating mechanism (32) and the said substrate (1) through the gas feeding pad (39), whereby the contact between the substrate and the irradiating mechanism is avoided at a time of carrying out a recording of a predetermined pattern by irradiating a beam.
