Abstract
PURPOSE: To detect an editing point surely by recording a PCM signal on plural tracks and by recording many kinds of error detection code in positions separated from the recording position by different distances.
CONSTITUTION: For example, PCM signal sequence H1, where horizontal parity code Qi is added for every data WiWWi+6, of odd-numbered four words of a PCM signal string is recorded on the first channel of a magnetic tape of three tracks, and similarly, PCM signal sequence H2 of even-numbered four words is recorded on the second channel. Then, vertical parity code Pi formed from one word taken out from sequences H1 and H2 and horizontal parity code Ri for every four words of code Pi are added, and the obtained signal sequence is recorded on the third channel through a delay circuit, etc., in a position, which is separated from signal sequences H1 and H2 by a prescribed distance, as parity signal sequence H4. Consequently, editing points can be detected surely on a basis of various parity codes independently of a small number of tracks at a reproducing time.
