Abstract

SERODS is a new technology for high-density optical disk storage based on the surface-enhanced Raman effect.⁽¹⁾ The SERODS technology is based on the principle that the enhanced light-emitting properties of certain molecules embedded in an optical medium can be altered at the molecular level to store information. When they are close to a rough metal surface, certain molecules emit a strongly enhanced light called surface-enhance Raman light which is characteristic of their vibrations. Normal Raman signals are generally very weak and cannot be easily detected. The enhanced emission is due to the Surface-Enhanced Raman Scattering (SERS) effect, which can enhance the Raman signal up to 10⁸ times.
