摘要： In recording of an interference fringe of a reference beam and a signal beam in a hologram recording medium, at the time of multiple recording of holograms in the same recording region by varying the angle of incidence of the reference beam on the hologram recording medium, the angular pitch of the incidence angle of the reference beam is varied according to the incidence angle of the reference beam in the manner of Δθ1, Δθ2, . . . , Δθm−1, and is thereby set to a minimum in such a range as not to worsen crosstalk. This makes it possible to increase the degree of multiplexing when the movable angle of the reference beam is the same, and to narrow the movable angle of the reference beam when the degree of multiplexing is the same, as compared with the related art.

摘要： At the time of varying the angle of a scan mirror for varying the angle of incidence of a reference beam on a hologram recording material, the angle of a slit is also varied in conjunction, whereby the beam diameter of the reference beam is varied by the slit so that the irradiation range on the hologram recording material will be constant without being varied according to the variation in the incidence angle of the reference beam. This ensures that the area of irradiation of the hologram recording material with the reference beam can always be kept constant, even when the incidence angle of the reference beam is varied at the time of recording holograms by the angle multiplex recording system.

摘要： A hologram duplication method is disclosed which makes it easy to duplicate a large number of holograms from a volume-recorded hologram, particularly from a hologram recorded in a recording medium of the disk type or the card type. N card type master recording media are prepared, and data pages are individually recorded on the N disk type master recording media without being multiplexed by changing the angle of a reference light beam among the N disk type master recording media. Thereafter, the data page recorded on each of the disk type master recording media is recorded on a common disk type duplication recording medium so that the data pages are N-multiplex recorded finally on the disk type duplication recording medium.

摘要： In order to ensure CAV recording/reproduction while preventing jitter increase and modulation decrease and thereby ensuring sufficient recording properties, even at a linear velocity in the range of 3.49 to 8.44 m/s, a first dielectric film, phase-versatile recording film, second dielectric film, reflection film and protective film are formed on a disc substrate having formed lands, grooves and wobbling on one major surface. The recording film is made of a GeInSbTe alloy, and the reflection film is made of an AgPdCu alloy or AlCu alloy. Composition of the GeInSbTe alloy is adjusted to contain Ge in the range of 1 to 6 wt %, In in the range of 2 to 6 wt %, and control Sb/Te in the range of 2.4 to 3.0. Composition of the AgPdCu alloy is adjusted to contain Cu not more than 1.5 wt %. Groove depth is controlled in the range of 30 to 40 nm, groove width in the range of 0.27 to 0.33 &mgr;m, thickness of the first dielectric film in the range of 65 to 80 nm, thickness of the recording film in the range of 12 to 18 nm, thickness of the second dielectric film in the range of 12 to 20 nm, and thickness of the reflection film in the range of 80 to 160 nm.
