Abstract :
We have developed a combined Raman scattering spectroscopy and disk property measurement system to evaluate crystallinity of SRR functional layer inside the rotaed optical disk. The CNR and Raman scattering spectrum can be measured simultaneously from Sb functional layer. Stokes and anti-stokes peak intensities of the spectrum were dependent and independent on the laser power. We have discussed that it is closely related to the SRR phenomenoin.
