发明名称 APPARATUS FOR REPRODUCING A VIDEO SIGNAL
摘要 A video signal reproducing apparatus comprises a rotary magnetic head which reproduces a video signal recorded on a magnetic tape, a rotator which rotates the rotary magnetic head to cause the same to scan the magnetic tape intermittently along a oblique path thereon, a head supporting member, such as a compound piezoelectric plate element, which supports the rotary magnetic head to rotate in accordance with the rotation of the rotator and to shift the position of the rotary magnetic head in the direction of the axis for rotation thereof in response to the level of a control signal supplied thereto, and a signal generator which produces a signal acting as the control signal in a "trick" reproducing mode and having such level variations as to cause the head supporting member to have a swinging movement in a period in which the rotary magnetic head is not in contact with the magnetic head, which affects to cancel a swinging movement of the head supporting member occuring in a period in which the rotary magnetic head scans the magnetic tape.
