METHOD FOR RECORDING DIGITAL SIGNALS ON MULTIPLE TRACKS OF A RECORDING TAPE ABSTRACT OF THE DISCLOSURE Disclosed is a method for recording digital signals on multiple tracks of a recording tape. Audio signals are quantized into digital signals are formed into data words and organized into a plurality of parallel rows which are adjacent to each other and respectively correspond to those tracks which are remote from an edge of the tape. Parity words are derived from the data words and organized into a row which is parallel to the rows of data words and corresponds to the track which is close to the edge of the tape. An error detecting check word is generated and appended to the end of each of the rows of data and parity words. A synchronization word is also generated and appended to the beginning of each of the rows of data and parity words. By the arrangement of the parity words along the same row or track adjacent to the tape edge, the probability of occurrence of incorrectable errors is reduced.
