    • A phase change optical recording medium includes at least a supporting substrate and a recording layer essentially consisting of AgInSbTe alloy compositions implementing recording and readout steps utilizing changes in reflectivity. The recording medium is characterized by the relation v0≧0.7 vWH, where the critical relative velocity of phase change, v0, defined by the value of v, at which the differential coefficient, −dR(v)/dv, reaches a maximum, when the recording medium moves against an optical unit during the recording steps at a relative velocity, v, ranging from minimum and maximum relative velocities warranted for the recording medium, vWL and vWH, respectively. When the reflectivity is measured with varying erase power PE at the linear relative scanning velocity v0, the reflectivity of the recording layer as a function of erase power, R(PE), preferably has a minimum. The recording layer has an activation energy of deterioration equal to or greater than 1.6 eV, which is obtained by measuring asymmetry, A, and calculating according to the equations, k=dt/dA, and k=k0×exp(Ea/kBT). The recording medium is also characterized by activation energy of displacement of the boundary, ranging from 1.0 eV to 2.4 eV, which is obtained from the rate of decrease in the area, S, of the amorphous regions as recorded marks with time according to Arrhenius' equation.
    • 相变光学记录介质至少包括支撑基板和基本上由AgInSbTe合金组合物组成的记录层,其实现利用反射率变化的记录和读出步骤。 记录介质的特征在于v0> = 0.7vWH,其中相位变化的临界相对速度v0由v的值定义,其中微分系数-dR(v)/ dv达到最大值, 当记录介质在记录步骤期间以相对速度v移动时,记录介质分别从记录介质vWL和vWH所需的最小和最大相对速度范围内移动。 当以线性相对扫描速度v0的变化的擦除功率PE测量反射率时,作为擦除功率R(PE)的函数的记录层的反射率优选地具有最小值。 记录层具有等于或大于1.6eV的激活能量,其通过测量不对称性A而获得,并且根据等式k = dt / dA和k = k0xexp(Ea / kBT)进行计算。 该记录介质的特征还在于边界位移的活化能为1.0eV至2.4eV,其从非晶区域的减小速率S得到,随着时间的推移,Arrhenius' 方程。
