A recording/reproducing method and apparatus for processing m-value (m is an integer at least equal to two) digital information data to produce recording data, for recording the recording data on an optical recording medium, for reading recording data from the optical recording medium, and for processing the read recording data to reproduce the information data as reproduced data. A predetermined relationship is established between information data x and n (n is an integer at least equal to two) of recording data y1-yn, and another predetermined relationship is established between reproduced data z and the recording data y1-yn.
