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
