Abstract

PURPOSE:To obtain a reproduction screen free from noises by including noises in the vertical blanking period of a video signal even during extremely slow motion reproduction. CONSTITUTION:When any voltage is applied to bimorph material 5, relative scanning angles of rotary magnetic heads Ha and Hb to magnetic tape TP are set by guide pin 4 so that scanning traces of rotary magnetic heads Ha and Hb in normal reproduction will nearly agree with recording tracks TR respectively. On the other hand, when bimorph material 5 is applied with a prescribed control DC voltage, the relative scanning angles of heads Ha and Hb to magnetic tape TP are varied by guide pin 4 so that the scanning traces of heads Ha and Hb in still picture reproduction will nearly agree with recording tracks TR respectively.
