摘要： An optical recording medium allowing high-density recording, where a groove having a shallow U-shaped cross section wider than certain width, a master for manufacturing optical recording medium, a manufacturing apparatus thereof, and a manufacturing method thereof are provided. A exposure beam (61) and a exposure beam (62) are recombined together with a first exposure beam (60) in a second PBS (47) so that traveling directions thereof may be the same direction. At this time, the exposure beam (61) and the exposure beam (62) are arranged so that both optical axes may be aligned at certain distance. Thereby, a width of a spot formed by combining these beams can be extended, and light exposure of the spot can be proper to form a shallow groove, as typically showed in FIG. 3.

摘要： An optical disc for recording an information signal having a plurality of states has a portion on which a groove is formed in a predetermined direction, and the groove has a nominal position in the direction perpendicular to the predetermined direction over a predetermined length that represents a first state the information signal. The disc also has a portion on which the groove is not formed that represents a second state of the information signal. The groove can also be displaced from its nominal position in the direction perpendicular to the predetermined direction over a predetermined length, the amount of the displacement representing at least one further state of the information signal. An apparatus for reproducing such a disc has a light source illuminating the optical disc, at least two detectors that each generate an electrical signal in response to light by the optical disc, a first and a second calculating circuit each for calculating at least one result signal in response to the electrical signals from the detectors, and a multiple-value signal generator that generates an output signal having a plurality of states in response to a first result signal from the first calculating circuit and a third signal. The third signal is derived from the first result signal and a second result signal from the second calculating circuit.
