A rotary head assembly, for example, for recording and/or reproducing video signals on a recording tape which is wrapped about at least a portion of the circumference of a tape guide drum, includes a primary support member moved in a circular path which is concentric with the guide drum, an intermediate support member, a first spring or springs connecting the primary and intermediate support members for yieldably resisting centrifugal movement of the intermediate support member relative to the primary support member, and a recording and/or reproducing head member or transducer connected to the intermediate support member by a second spring or springs providing the head member with a natural frequency of movement relative to the intermediate support member which is suitable to cause the head member to follow high frequency vibration of the tape and to reduce hunching of the latter at the location where the head member first contacts the tape, and which is substantially greater than the natural frequency of the centrifugal movement of the intermediate support member relative to the primary support member so that such centrifugal movement can ensure the adequate contact of the head member with the tape in response to movement of the primary support member in its circular path.
