ABSTRACT:
A reproducing system having a rotary magnetic head scanning video tracks recorded on a magnetic tape, a head deflector for deflecting the rotary magnetic head transversely to the tracks scanned, and a control circuit for supplying a control signal to the head deflector so that the rotary magnetic head scans the center of the video tracks. The control signal is produced by comparing the envelope of reproduced signals from the rotary magnetic head when one track is scanned with the envelope of reproduced signals when another track is scanned.
