Paper Abstract

The optical system for high-speed #-D data recording in the volume media is considered. The increase of speed and density recording by more than one order is reached through the usage of: The radial deflection of the light beam on the basis of the scanner with the accompaniment of 'a traveling acousto- optical lens' Multilayer recording of microgratings and multilevel phase data coding. The heterodyne phase-sensitive method of reading. The evaluation of speed and bit density is given.
