A method for editing a PCM signal in which a first redundant code series is added to a PCM word in a first arranging state and a second redundant code series is added to the PCM word and the first redundant code series in a second arranging state after being interleaved. When a desired data is intended to be edited from a master tape on which such PCM data as set forth was recorded the first PCM, data as well as the first and second redundant code series are supplied to a recording encoder so as to restrict an initial value of an interleaving circuit provided in the recording encoder to the value same as that already recorded. Also an editing apparatus is described.
