Abstract: A magnetic recording medium comprises a non-magnetic substrate and at least one layer of obliquely deposited magnetic crystals which contains, as a main constituent, Co or a Co--Ni based alloy containing Cr in an amount within the range of 2 to 8 atom % and has a density of 5.0 g/cm.sup.3 or more, said layer being formed on said non-magnetic substrate.

Abstract: A magnetic recording medium comprises a non-magnetic substrate and at least one layer of obliquely deposited magnetic crystals which contains, as a main constituent, a Co-Ni based alloy containing Cr in an amount within the range of 2 to 8 atom % and which is obliquely deposited on the non-magnetic substrate in such a manner that the minimum angle of incidence of a vapor stream of a magnetic material with respect to the line normal to the non-magnetic substrate is 45.degree. or less.

Abstract: A magnetic recording medium comprises a non-magnetic high-molecular film and at least one magnetic layer containing Co, Ni, Cr and oxygen and formed on the non-magnetic high-molecular film by an oblique incidence vacuum deposition method. The Cr content is within the range of 2 to 8 atom %, the content of oxygen is within the range of 5 to 25 atom %, and the ratio of the number of oxygen atoms to the number of Cr atoms is within the range of 2:1 to 10:1.

Abstract: A magnetic metal deposition material contained in a hearth is heated and evaporated in a vacuum to form a flow of vapor, which is then ionized and converged toward a predetermined deposition surface of a flexible substrate. The flexible substrate is moved obliquely downwardly along a convex course by sliding contact with the curved surface of a fixed curved guiding body between a pair of guide rollers located at different heights above the hearth. The fixed curved guiding body communicates with a coolant source for cooling the substrate moving in contact therewith and may be provided with oscillators. Thus a thin film of the magnetic metal is deposited on the convex surface of the substrate.

Abstract: A method of making a magnetic film target for use in sputtering characterized by forming a film of a magnetic material on a substrate by ion-plating a raw magnetic material thereon. The raw magnetic material is either identical with the magnetic film material or an ingredient or ingredients for constituting it. In the latter case, one or more metallic ingredients are simultaneously ion-plated in the same system to form a magnetic alloy or compound film on the substrate. To prepare a magnetic alloy target in which the composition changes in the thickness direction, the ion plating ratio of respective metallic ingredients is changed with time.

Abstract: A magnetic recording medium having a thin magnetic amorphous rare earth metal-transition metal alloy film is disclosed, the amorphous alloy film having an axis of easy magnetization in a direction substantially vertical to the film surface and containing a crystalline phase in the amorphous phase. The magnetic recording medium exhibits high coercive force over a wide compositional range.

Abstract: A thermodevelopable photographic material comprising a support and a layer composed of (a) a high silver ion conducting substance having an ion conductivity at 25.degree.C of at least 1 .times. 10.sup.-.sup.3 (.OMEGA.cm).sup.-.sup.1, such as silver iodide tungstate, or a mixture of the high silver ion conducting substance with silver, and (b) a weak reducing agent. In order to increase the sensitivity of the material, a photosensitive silver halide can further be incorporated in the layer. The photographic material is exposed imagewise, and then heated for a short time to form a permanent visible image of clear contrast.
