    摘要： A recording member having a predetermined substrate, and a thin film which is formed on the substrate and which is formed with recesses or pits for recording information when irradiated with a working beam, characterized in that said thin film is formed of an inorganic material which contains at least arsenic, selenium and tellurium, and that a distribution of either of said Se and said Te decreases from a part near the surface of said thin film towards a central part thereof, while a distribution of said As increases from a part near the surface towards said central part, is disclosed. This recording member can afford a high signal-to-noise ratio and a long lifetime. It is preferable that the distribution of said Se decreases so as to be at least 50 atomic-% in terms of the content of said Se in a part being the closest to the surface of said thin film and to be at most 40 atomic-% in terms of the average content of said Se over the whole thin film, and that the distribution of said As increases so as to be at most 15 atomic-% in terms of the content of said As in the closest part and to be 5 to 35 atomic-% in terms of the average content of said As in said whole thin film. The Se-Te-As-based material may well be doped with at least one element selected from the group consisting of Ge, S, Tl, Sn, Pb, In and Ta, within a range of 2 to 15 atomic-%.

    摘要： A recording medium having at least a first inorganic material layer which overlies a predetermined substrate and which exhibits a light absorptivity for projected light, and a recording layer which overlies the first inorganic material layer and whose principal component is an organic material. The first inorganic material layer contains at least one element selected from the group consisting of In, Bi, Te, Sb, Ge, Sn, Pb, Cr, Nb, Ni, Pd, Fe, Pt, Re, Ta, Th, Ti, Zr and Tl and the content of the element or elements is at least 65 atomic-%.Further, the first inorganic material layer may well be overlaid with a second inorganic material layer which exhibits a light transmissivity higher than that of this first inorganic material layer. Preferable as the material of the second inorganic material layer is an inorganic material which contains at least one element selected from the group consisting of In, Bi, Te, Sb, Pb, Ge and Sn and at least one element selected from the group consisting of S, Se and O.In proximity to at least one surface of the first inorganic material layer, at least one stabilizing layer may be disposed as well.

    摘要： A recording member in which a bismuth-antimony alloy thin film containing antimony as its indispensable component is deposited on a predetermined substrate is disclosed. The Sb content of the film lies in a range of from 1 % to 15 % inclusive in terms of the average atomic-%. Preferably, the Sb content has the average value held in the specified range, and it is gradually increased in the thickness direction of the film so that in the part near the substrate and/or front surface of the film, the maximum content may lie within a range of at most three times the average content of other part of the film.

    摘要： When recording domains are formed locally on a recording medium and information is recorded and reproduced by using rise and fall in a reproduced waveform obtained from the recording domains as data, timing patterns indicating start of demodulation are recorded for the lead-edge and the tail-edge of the recording domains, respectively; time interval between the timing signal for starting demodulation detected from the rise in the reproduced waveform and the timing signal for starting demodulation detected from the fall in the reproduced waveform is detected; time shifts of the signals detected from the lead-edge and the tail-edge of the recording domains succeeding the timing patterns for starting demodulation by using the time interval thus detected; and the information is stably detected as time sequential data having no jitter.
