ABSTRACT:
In apparatus for supporting a magnetic transducer or head in a video tape recorder and which includes a cantilevered support member mounted at one end, for example, on a rotary portion of a tape guide drum, with the head secured on the opposite or free end of the support member in transducing relation to the tape wound about the drum; at least a part of the support member extending from its mounted end is constituted by a bi-morph leaf, and conductive layers are bonded to opposite surfaces of the bi-morph leaf and are absent from at least the free end portion of the support member so that flexing of the bi-morph leaf occurs between the conductive layers in response to the application of a drive signal to the conductive layers for deflecting the head laterally in respect to the plane of movement of the head with the rotary drum portion, and such flexing is excluded from at least the free end portion of the support member for facilitating the secure attachment of the head thereto and for minimizing the angular deviation of the active face of the head from the tape that accompanies the lateral deflecting of the head.
