Paper Abstract

High-density Optical storage technology which uses a 405 nm laser and an objective lens of high numerical aperture (NA)of 0.85 is developing rapidly due to its high capacity over 23 GB on a single layer of a 120mm-diameter optical disc and great commercial demands. New storage media have been the bottleneck in high density optical storage. Organic material can be an attractive optical storage medium with various advantages, such as good sensitivity, easy fabrication, reasonable cost and structural flexibility, etc, compared with inorganic storage material. Efforts have been made to seek for new organic storage materials with high performance matching the 405 nm short wavelength laser. In this paper, recent progresses in developing organic materials as recording media for high density blue laser optical storage are presented. The recording mechanism of recordable dye layer and basic requirements for the dye materials are analyzed and discussed.
