INFORMATION SAVING METHOD USING LIQUID CRYSTALLINE POLYMER

摘要

The method provides an optical information storage media with reversible information saving function so that we can write, store, erase and rewrite information on the media. The method comprises the steps of: (A) making a thin film by dissolving the liquid crystalline polymer into an organic solvent; (B) heating the solvent to the melting temperature of the crystalline polymer, cooling the solvent below the glass transition temperature, and use the fixed thin film as storage layer; (C) melting the liquid crystalline polymer by irradiation of polarized ultraviolet through a photo mask; (D) storing the information by cooling the polymer.
