Abstract
A rotary head deflection apparatus for allowing magnetic heads 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 wound onto a stator and movable members carrying magnetic heads and magnets, so that the driving coils are energized to enable the magnetic heads to be displaced in the direction of the axis of rotation of the rotary member.
