| Abstract: | The initialization conditions have great effect on the reflectivity contrast and CNR of Ag 11 In 12 Te 26 Sb 51 phase change optical disk.It is indicated that the reflectivity contrast increases as the initialization power increases and decreases as the initialization velocity increases.Also the reflectivity contrast is very different when the measurement wavelength ranges from 400 to 900nm.The CRN of Ag 11 In 12 Te 26 Sb 51 phase change optical disk first increases and then decreases when the initialization power and velocity increase.The most favorable initialization conditions are those that power ranges from 1300 to 1500mW and velocity ranges from 3.6 to 4.8m/s. |
