Abstract
A head rotation apparatus for mounting and rotating the record/reproduce heads of a video tape recorder includes a head drum having a planar main face formed thereon in a plane perpendicular to the axis of rotation of the heads, one or more fixed heads fixedly attached to the head drum with a planar lower surface of each head abutting directly against the head drum main face, and a voltage-sensitive deflection member having a planar main face with at least one movable head fixedly mounted on a tip portion of the latter main face, with an attachment portion of the deflection member main face being held abutting directly against the planar surface of each fixed head. The fixed and movable heads are thereby accurately aligned with respect to the direction of the axis of rotation of the heads, with a very simple mechanical configuration.
