ABSTRACT:
When recording a PCM signal, particularly an audio signal, on the oblique tracks of a magnetic tape, e.g. for example of a videorecorder, errors occur in the digital signal during the change of heads. These errors are removed in that, in the region where the scanning of the heads overlaps, phase matching of the bit clock pulses is effected, the bit patterns are matched and the number of bit clock pulses is increased or reduced before the next change of heads.
