<p>A rotary head deflection apparatus for allowing magnetic heads (2, 3) to properly scan signal tracks recorded on a magnetic tape, and used for a helical scan system video tape recorder, which is constituted of driving coils (8a, 8b) wound onto a stator (9) and movable members (4, 5) carrying the magnetic heads (2, 3) and magnets (6a, 6b, 7a, 7b) so that when the driving coils (8a, 8b) are energised, the magnetic heads (2, 3) are displaced in a direction parallel to the axis of rotation of a rotary drum (1).</p> |
