    摘要： When using an optical disc medium that includes pit trains having their widths narrower than a diffraction limit, it is difficult to detect a tracking error signal and take a tracking-servo control while increasing pit density in a direction orthogonal to a pit-train extension direction. Information pit trains are arranged spirally or concentrically and formed in a structure in which their depths are changed periodically at a pitch radially along the optical disc medium, so that the tracking error signal can be obtained by push-pull detection of diffraction light from the structure.

    摘要： There is provided a method for forming a Ge—Sb—Te film having a composition of Ge2Sb2Te5 on a substrate by a CVD method using a gaseous Ge source material, a gaseous Sb source material and a gaseous Te source material. The method includes loading the substrate within a processing chamber (Process 1); performing a first stage film forming process on the substrate by supplying the gaseous Ge source material and the gaseous Sb source material (Process 2); and performing a second stage film forming process on a film obtained through the first stage film forming process by supplying the gaseous Sb source material and the gaseous Te source material (Process 3). The Ge—Sb—Te film is formed by the film obtained through Process 2 and by a film obtained through Process 3.

    摘要： An information recording medium of the present invention includes a recording layer whose phase changes by irradiation with a laser beam or application of current. The recording layer contains, as its main component, a composite composed of Ge and Sb that are essential components, and Te that is an optional component. The composite has a composition within a region enclosed by: point (a) (35, 65, 0), point (b) (36.9, 60, 3.1), point (c) (3.2, 60, 36.8), and point (d) (5, 95, 0) in terms of a coordinate (Ge, Sb, Te)=(x, y, z) on the triangular coordinate shown in FIG. 1, where point (b) corresponds to a point at Sb=60 on Ge60Te40—Ge35Sb65, point (c) corresponds to a point at Sb=60 on Te—Ge5Sb95, and the region includes lines extending between point (a) and point (b), point (b) and point (c), point (c) and point (d), and point (d) and point (a).

    摘要： An optical information recording medium having the same recording volume as that of DVD-ROM is obtained which shows excellent characteristics at recording linear velocities within a range of twice linear velocity of DVD (about 8.2 m/s) to five times liner velocity of DVD (about 20.5 m/s) and excellent archival stability, by a construction including a transparent substrate, a recording layer which is formed on the substrate directly or with another layer interposed therebetween and can change in phase reversibly by a laser beam irradiation, wherein the composition of the recording layer is within a region bounded by composition points A(41.2, 7.4, 51.4), B(39.8, 10.5, 49.7), C(28.5, 21.7, 9.8), and D(30.6, 15.8, 53.6) in a triangular coordinate graph represented with a coordinate of (Ge, Sb—Bi, Te) and a Bi content in the recording layer is 4 atom % and more and less than 13 atom %.
