ABSTRACT ROTARY TRANSDUCER HEAD ASSEMBLIES A rotary magnetic head assembly for a helical scan video tape recorder comprises a tape guide arrangement 2 for guiding a video tape 1, the tape guide arrangement 2 including coaxial rotatable and fixed drums 5 and 6 and tape guides 3 and 4, a pair of parallel-aligned bi-morph leaves 22 and 23 secured to the rotary drum 5, a pair of elastic plates 28 fixed on respective free ends of the pair of bi-morph leaves 22 and 23, a rigid portion 28 bridging the elastic plates 29, and a video head 9 mounted on the rigid portion 28. When the bi-morph leaves 22 and 23 are deflected in response to a control signal to follow a track 11, 12 or 13 on the video tape 1, the elastic plates 29 self-deflect such that the tape-contacting surface of the video head 9 remains aligned with the surface of the video tape 1.
