摘要： An optical recording and reproducing medium has grooves formed thereon along recording tracks, this optical recording and reproducing medium being recorded and/or reproduced with irradiation of light having a predetermined wavelength λ. Since the grooves are composed of a first groove 2 and a second groove 3 shallower than the first groove 2 and the second groove 3 is disposed adjacent to both sides of the first groove 2, a recorded signal can be suppressed from crossing the tracks and a sufficiently large amplitude amount of a push-pull signal can be obtained. Thus, an optical recording and reproducing medium can produce a stable tracking signal and hence a recording density can be increased.

摘要： On a magneto-optical disk, a first groove Gv1, a second groove Gv2, and a third groove Gv3 are formed so as to be adjacently arranged. The first groove Gv1 and the second groove Gv2 are deep grooves, and the third groove Gv3 is a shallow groove. The first groove Gv1 and the second groove Gv2 are formed by being wobbled. Data is recorded on four recording tracks of the two deep grooves and two lands between the deep grooves and the shallow groove. A CTS signal is obtained by a sum signal (A+B+C+D) of a photo-detector 6, and a push-pull signal is obtained by a difference signal (A+D)−(B+C) of a photo-detector 8.

摘要： A recording method whereby an inorganic resist made of an incomplete oxide of a transition metal is formed as a film onto a substrate and a latent image corresponding to pits is formed onto the inorganic resist by exposure. The exposure is performed by a laser beam whose intensity has been modulated by a pulse signal whose pulse height decreases in a rear portion in a length direction of the pit, thereby forming a format of a track pitch smaller than a recording beam diameter (track pitch/exposure beam diameter=0.333 to 0.833).

摘要： An optical recording medium used as a recording medium for information signals in which, in forming a groove along a recording track, a first groove and a second groove are formed to a first depth x to describe a double helix and a third groove having a second depth y shallower than the first depth x is formed between the first and second groves describing double helices. By setting the phase depths of these grooves to a pre-set range, signals required for tracking servo or seek are obtained to sufficient levels to realize stable tracking servo and seek.

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： The stable reproduction of wobble signal without generating beats despite of an improvement in recording density by narrowing a track pitch is realized. Data by magnetooptical recording is recorded on wobbling grooves and lands between adjacent wobbling grooves. The wobbling grooves are provided to wobble both sides of the grooves in different amplitudes. Further, both the sides wobbled in different amplitudes are wobbled in phase in the track direction. These different amplitudes of both sides are preferably set to 3.3 to 40%.
