Abstract
We present results of the feasibility study on photoaddressable polymers (P APs) applied to optical disc systems. PAPs represent a new class of organic rewritable materials that exhibit a huge signal birefringence (Deltan) at the readout wavelength. By optimizing the disc structure and the readout op tics, the signal amplitude is proved to be sufficient for the optical disc systems. A low noise profile and sharp recording profile led to a maximum c arrier-to-noise ratio (C/N) of 58 dB and a clear eye-pattern. They also sho wed a potential for multi-level recording, since the recording was dominate d by a pure photon mode.
