PCT No. PCT/JP94/00844 Sec. 371 Date Mar. 2, 1995 Sec. 102(e) Date Mar. 2, 1995 PCT Filed May 27, 1994 PCT Pub. No. WO94/28546 PCT Pub. Date Dec. 8, 1994A digital data error correction processing method and apparatus suited for high density recording in a high definition VTR etc. When the number of tracks per field is N, the digital data recorded, for example, the video signals, are given at least 1/N outer codes for each block in the block outer code ECC circuit (4A). Further, the outer codes and inner codes are made product codes in configuration, the inner codes are added at the block inner code decoding circuit (14A), and the outer codes among the double construction error correcting codes are dispersed over one field's worth of N number of tracks to be recorded on a magnetic tape (1).
