Optical information recording medium and recording/reproducing method therefor
Abstract:
An optical information recording medium in which recorded information is stably stored for long time in the initial state, signals are not deteriorated by a laser beam for reproduction at the time of signal reproduction, the quality does not change in normal long-term storage, the write characteristic is held, a manufacturing cost is reduced, a margin in the manufacture process is assured, and excellent recording/reproducing characteristics are obtained in the wide range of linear speeds and recording powers is provided. An optical information recording medium 1 is formed by sequentially stacking a first information recording layer 11, an intermediate layer 12, a second information recording layer 13, and a protection layer 14 on a substrate 10. As a material of a recording layer 13b of the second information recording layer 13, a material having a composition expressed by [(ZnS)x(SiO2)1-x]y(SbzX1-z)1-y (where 0
