摘要: An optical storage medium including a transparent polymer and an isomerizable AZO dye, the being coated as water miscible solution on substrate so to form film having thickness of from μm 100 storing information through birefringence diffraction efficiency greater than 40% at 1 millisecond response time. The dye remains in is present concentration 4.5% 25% based weight film.
