A signal converting method comprises the steps of converting the continuation of a binary signal representative of data into the continuation of blocks including a binary signal of at least two bits, converting the continuation of the blocks into the continuation of a ternary or higher signal, the blocks differing in the data arrangement therein from each other corresponding to the different bits of the signal level of the ternary or higher signal, and substituting, if a predetermined number of bits indicative of the same signal level continue in the continuation of the ternary or higher signal, a special bit having a signal level differing from the signal level of any other bit for the last one of the predetermined number of bits.
