【Abstract】 In this paper, the characteristics of new gene variant (BR M1B) and its behavior of the writing, reading and erasing of the information in a bacteriorhodopsin film are investigated. A system of three-wavelength EDRAW (Erase Direct Read After Write) was constructed. Optical data was written into BR film with 670 nm laser based on the B to P photochemistry reaction. Then the information was erased with 490 nm laser based on the reconversion of the photoproduct state P. The resulting data could be read out with 594 nm laser based on the differential absorption of B and P states.更多还原
