Abstract: Erasable optical memories for storing information are prepared from organic materials having two stable crystalline forms. Each crystalline form has at least one different optical characteristic and the materials are reversibly thermally convertible between the crystalline forms. Information is recorded or erased with a laser beam that heats a film of the organic material in a local area to change the crystalline form. Information may also be recorded or erased by melting a local area or all of the film and quickly cooling it to restore the original crystalline form. Examples of such organic compounds are biaryl compounds, such as binaphthyls, bianthryls and biquinolyls.
