A multi-level data processing method converts a binary data into a multi-level data having n bits per symbol, where n is an integer satisfying n>=2. A {(n-1)xm}-bit binary data is arranged in upper (n-1) bits of multi-level data of m symbols, where m is an integer satisfying m>=2, and a (m-k)-bit binary data is converted into m bits according to a predetermined conversion rule and arranged in a lower 1 bit of the multi-level data of m symbols, where k is an integer satisfying m>k>=1, so as to convert a (nxm-k)-bit binary data into 1 set of multi-level data made up of m symbols.
