Abstract: A vitreous film containing, e.g., 30 - 90 wt. % of Sn, 1 - 20 wt. % of P, 0,1 - 20 wt. % of Pb, 2 - 30 wt. % of 0 and 5 - 35 wt. % of F is formed by vapor deposition on a substrate such as glass, metal, plastic or ceramic. A light-absorbing substance can be incorporated in the vitreous film to provide a recording layer for a heat-mode optical recording medium capable of causing decoloration or formation of pits on irradiation with a laser beam.

Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for inspecting an orientational direction of a material having a long-period regularity ranging from several nm to several hundreds nm in a short time. SOLUTION: In this method and its device for evaluating long-period regularity of a sample, a process 1 and a process 2 are carried out, and long-period regularity of the sample is evaluated from a plurality of X-ray diffraction profiles provided by the processes 1, 2. In the process 1, a part or all of primary X-rays 2 radiated from a rectangular X-ray source 1 is incident on the surface of a measurement sample 5 arranged in parallel to the major axis of the X-ray source at an incident angle within 5 deg., and an X-ray intensity distribution of X-rays diffracted on the surface of the sample is measured with a diffraction angle 2 θ by means of a 0-demensional detector 8 or a one-dimensional detector for providing an X-ray diffraction profile. In the process 2, the measurement sample is turned by a predetermined angle within the measurement sample surface, and the process 1 is repeated once or more.
