| Abstract | ||
| The effect of absorption coefficient on the optical storage system MR/BDK have been studied, optical storage system was prepared from example of methyl red (MR) in different degrees of acidity and mixed with benzyl dimethyl ketal (BDK) as aphotoinitiator in acertain rates of size, the optical properties measured by using a variable angle spectroscopic ellipsometry instrument. And the relation between the optical characterestics of the system and the absorption coefficient studied as well it has become clear that the increase of basic concentrations of the system, this leads to decrease of the used wave lenglength, and this in turn leads to increase of storage ability of the data, from this we obtain the result that the disks which prepared by basic concentras lions are better than that prepared from acid concentrations, and add this information to the library of programming of spectrum device. Keywords: optical storage system, absorptiom coefficient, benzyl dimethyl ketal (BDK), variable angle spectroscopic ellipsometry. | ||
