Abstract
A magnetic tape recorder for video recording and video playback with a one head drum and a head support plate. According to the invention the head support plate is point supported and spring attached to a base plate. The head support plate is movable around two rotation axes and is actuated with an electromagnetic drive means. The one motion cooperates with a dynamic track following circuit for providing dynamic height level correction of the head and allows to capture tracks during replay, which deviate from the parallel inclined position or, in case of a course of the track deviating from the tape recording speed resulting in a trick palyback. The motion around the other axis allows a controlled and regulated azimuth offset of the neighboring tracks during playback, which are recorded with continuously alternating azimuth angle.
