In particular, a two-value data train of “0” and “1” is converted into another data train of three values of “0,” “1” and “−1” in accordance with a rule for encoding determined in advance, and the amplitude “0” is allocated to pixels of the value “0”; the amplitude “1” (phase “0”) is allocated to pixels of the value “1”; and the amplitude “1” and the phase “π” are allocated to pixels of the value “−1,” to carry out recording.
