High Density Optical Memory.
Abstract
Fourth quarter activities included research into electron coloration techniques, investigation of acousto-optic deflector and optical system parameters, construction of computer interface and memory control electronics and the construction of a mechanical scanner for demonstrating high density digital and audio recording. Results included the discovery that highly pure KCl:NaCl could be electron colored at room temperature. The resulting crystal was stable at a higher temperature than one colored at liquid nitrogen temperature. Difficulties in obtaining satisfactory resolution with the two axis acousto-optic deflector were traced to unsatisfactory lenses in the optical system.
