Abstract
In a video tape recorder of the helical scan type, two auxiliary magnetic heads having different azimuth angles are provided in the vicinity of two main magnetic heads. The main and auxiliary magnetic heads have their tracks aligned so as to compensate for the reduced period of the reproduction signal of the main magnetic heads during high speed reproduction by using the reproduction signals of the auxiliary magnetic heads. Thus, blur free high speed reproduction pictures may be realized, and, at the same time, a dancing picture correction during still reproduction may be facilitated.
