The thermal stability and glass forming ability play a dominant role in deciding the usefulness of the material for optical storage media. Another important aspect is the long achievability of the material used for memory point of view. This can be seen by checking the effect of age on the samples. In fact after alloying, the material is melt quenched and the changes take place very rapidly. However, with passage of time, the possibility of change cannot be ruled out and there are the cases, where it has been observed that there are some changes is structures. In the present paper, the effect of age has been studied on the same samples using the DTA technique with the samples heated at several uniform heating rates. The samples have been analyzed from time to time, while the emphasis has been given to the samples analyzed once after 3 months and then after 6 months. The effect of age has been observed on the glass transition temperature (Tg) with composition variation at different heating rates. The experimental studies reveal that there is no significant change in the first 6 months which is the most crucial time.
