A method for increasing the information capacity and enhancing the rel
iability of information storage in a dynamic fibre-optic memory is pro
posed. An additional built-in channel with counterpropagting circulati
on of signals is provided for this purpose. This additional channel ca
n be used to transmit both information and service signals, such as ad
dress wards, clock signals, correcting sequences, etc. The possibility
of compensating the attenuation of an information signal by stimulate
d Raman scattering is considered.
