Scanning arrangement for fast access of memory and display

Abstract

An access system based on piezo-electric transducer assembly or electro-optic device light beam deflector assembly which on application of electric signals deflects light beams, which are then passed through total internally reflecting surfaces to increase the separation between beams, is described. The light beams fall on large area information storage surface, such as optical disk or magnetic disk, for the purpose of reading and writing. The access time to the information is very fast. The nature of the reflected light from the memory surface is detected to read the digital signals stored on the surface as is conventionally done in the art. Except for the small friction-free movements of the piezo-electric transducers there are no moving parts for access to the storage surface. Instead of the memory surface a screen may be placed when tthe light beams can be used after large separation to form a fast display.
