摘要： A phase-change optical recording medium capable of performing recording and reproduction at a high speed is provided, in which a reproduced signal output is not only sufficiently large but the phase-change optical recording medium also has excellent repeated rewriting performance. An interface layer 3, which is composed of a Ge—Si—N-based material, is formed on at least a surface of one side of a recording layer 4 of the phase-change optical recording medium 10. Accordingly, even when a phase-change material having a high melting point, for example, a Bi—Ge—Te-based phase-change material is used for the recording layer 4, it is possible to provide the phase-change optical recording medium in which the reproduced signal output is sufficiently large and the repeated rewriting performance is excellent.
摘要翻译：提供能够以高速进行记录和再现的相变光学记录介质，其中再现信号输出不仅足够大，而且相变光学记录介质也具有优异的重复重写性能。在相变光记录介质10的记录层4的一侧的至少一个表面上形成由Ge-Si-N基材料构成的界面层3。因此，即使使用具有高熔点的相变材料（例如Bi-Ge-Te类相变材料）作为记录层4，也可以提供相变光记录介质其中再现信号输出足够大并且重复的重写性能优异。

摘要： An information-recording method includes the steps of moving a light beam at a selected linear velocity relative to the information-recording medium; controlling the light beam to generate a multi-pulse having at least three power levels of a first power level Ph, a second power level P1 which is lower than the first power level, and a third power level Pm which is intermediate therebetween, the multi-pulse being repeatedly modulated between the first power level Ph and the third power level Pm; adjusting the third power level Pm in response to the selected linear velocity; and recording the information by irradiating the information-recording medium with the controlled light beam. Recording compatibility can be secured for information-recording apparatuses different in recording linear velocity and laser source characteristic.

摘要： An information-recording method and an information-recording medium which make it possible to improve overwrite characteristics in the high speed recording, especially archival overwrite characteristics for overwriting information after retaining the medium in a high temperature environment for a certain period of time, and an information-recording apparatus based on the use of the same are provided. The information-recording method comprises overwriting a random pattern with light beams having a predetermined recording power and a variety of erasing powers; reproducing the random pattern to determine a minimum value Pb1 and a maximum value Pb2 of the erasing power obtained when the pattern, in which a reproduction jitter exceeds a predetermined threshold value, is erased; determining an optimum erasing power Pb from the minimum value Pb1, the maximum value Pb2, and a relational expression represented by Pb=α×Pb1+(1−α)×Pb2; and recording the information with the determined optimum erasing power Pb. The value of α is previously recorded on the information-recording medium. The information-recording apparatus has a Pb-calculating control unit which reads the value of α when the optimum erasing power Pb is determined.
