ABSTRACT:
A helical-scan recorder for two-channel digital video recording comprises two pairs of write-read heads which are situated diametrically opposite each other. To simplify tracking it is proposed to record tracking, signals of different frequencies with one head of each of said pairs of heads and to read said tracking signals during recording via crosstalk, each time using the other head of each of said pairs of heads.
