Abstract
In a method of recording digital information signals to form tracks on a magnetic tape, the samples of the signals to be recorded are divided into a plurality of odd sample groups and a plurality of even samples groups. The groups containing adjacent samples are disposed on differently-numbered regions of different tracks. Error correcting codeword may be recorded in a plurality of tracks. Errors in one region can be corrected or compensated by samples in different tracks or samples in differently-numbered regions.
