ABSTRACT:
A recording method includes the steps of generating recording data in such a manner that, when m-bit data is converted into a data symbol of n bits (m<n), and connection bits such that the summed value of DC components per unit time decreases are selected from among a plurality of connection bits and are added after the m-bit data symbol, the connection bits differing from connection bits which are added when the n-bit data symbol is a data symbol other than the special data symbol are added to generate recording data; and recording the generated recording data on a recording medium.
