Abstract

A novel optical storage media based on the optical alignment of liquid crystals is reviewed. The high birefringence of the liquid crystal combined with the high spatial and angular control of the liquid crystal orientation using light can lead to new, high capacity, optical storage media. Our work demonstrating that monomeric optically aligned liquid crystal can be subsequently photopolmerized to form stable polymer films further allows for the use of this technology for read-only storage media. Issues regarding the advantages and disadvantages of these potential storage media will be discussed.
