ABSTRACT:
A digital signal recording circuit for transmitting data signals and clock signals over respective rotary transformers quantizes the data signals transmitted by the rotary transformer and feeds back the quantized data signals. The data signals quantized and fed back in this manner are latched by the clock signals transmitted by rotary transformer. With the present digital signal recording circuit, broad-range signals of from the direct current to a high frequency may be transmitted for recording correct data signals.
