Abstract :
Summary form only given. The data-storage capabilities of the photochromic material biochrom, a film based on bacteriorhodopsin (BR) embedded into a polymeric matrix, are described. The material is capable of recording optical information (upon exposure to light) with constant and reversible storage at high spatial resolution (>5×103 lines/mm), photosensitivity up to 10-3 J/cm2, and high cycling (104 cycles). Various types of recording (holographical, polarizable, by bits, etc.) are possible. Image recording is performed by yellow light and its erasure by blue light
