5. The method for PCM signal recording as claimed in claim 1 characterized in that said step of distributing said words in said channels according to said predetermined distribution matrix pattern includes the step of sequentially distributing a sequence of a predetermined number of words of the PCM signals so that these words are sequentially distributed in the respective recording tracks, whereby the order of words recorded in one recording track is modified.
1. A method for PCM signal recording wherein each channel of a multiple channel input PCM signal formed of a plurality of words is subjected to distribution to a plurality of recording tracks, characterized by the steps of selecting the number of tracks in which each said channel is to be divided, determining a distribution matrix pattern for said input signal words over said selected number of tracks, distributing said words in said channels to said recording tracks switching distributing means in accordance with said determined distribution matrix pattern, and in that the PCM signals composed of the distributed words and corresponding to the respective tracks are supplied to a plurality of recording heads via a corresponding plurality of separate encoders adapted to correct for coding error so that recording is made in such a manner that a plurality of recording tracks, determined in number as the product of the selected number of tracks and the number of channels, are formed on a recording medium.
