ABSTRACT:
A rotary magnetic head assembly for a helical scan video tape recorder comprises a tape guide arrangement including coaxial rotatable and fixed drum portions about which a video tape is helically guided, a pair of substantially parallel bi-morph leaves each secured, at one end, to the rotary drum portion and being both deflectable in the same direction in response to the application of a control signal thereto, and a deflectable member carrying a transducer head and being connected to the opposite free ends of said bi-morph leaves, such deflectable member having at least portions thereof which are elastically flexible and located between the free ends of the bi-morph leaves and the head to deflect in response to deflection of the bi-morph leaves for maintaining the head in proper contacting relation to the tape guided about the drum portions.
