The mathematical simulation of the switching processes in an MO linear light modulator with slitlike channels on high-coercive crystal of YFeO3 is carried out. For switching to be completed in 0.15 microsecond(s) it needs control current impulses of 0.8 - 1.2 A in amplitude and 0.1 microsecond(s) in duration that are experimentally confirmed. The realized laboratory model of the 32-channel controlled modulator for the system of information storage in the form of 1-D holograms admits the normal operation, provided switching rates are about 100 kbit/s in each channel. The higher rates of switching demand the use of special electrodes, crystal substrates, and cooling systems.
