ABSTRACT:
When modulating by an interleaved NRZI technique by inserting one bit per every m bits of input data series, the frequency characteristics of bit rows varying by the polarity ("0" or "1") of the bit to be inserted are compared, and the bit row closer to the desired frequency characteristic is selected as the output series, so that recording is effected by controlling the frequency characteristics of the digital signal.
