Abstract
Disclosed herein is a method of manufacturing a data storage media comprising mixing a photochromic dye with an organic material or an inorganic material to form a holographic composition; and molding the holographic composition into holographic data storage media. Disclosed herein too is an article comprising a photochromic dye and an organic material, wherein the article is used as a data storage media. Disclosed herein too is a method for recording information comprising irradiating an article that comprises a photochromic dye; wherein the irradiation is conducted with electromagnetic energy having a wavelength of about 350 to about 1,100 nanometers; and reacting the photochromic dye.
