ABSTRACT OF THE DISCLOSURE The present invention relates to a rotary head assembly, for example, a rotary head assembly for recording or reproducing video signals on a recording tape wrapped at least partially around the tape guide drum of a video tape recorder. The head assembly includes a primary support, an intermediate support and a recording and/or reproducing head. The primary support is moved in a circular path concentric with the guide drum. The intermediate support is connected to the primary support by a first spring which yieldably resists centrifugal movement of the intermediate support relative to the primary support. The recording and/or reproducing head is connected to the intermediate support by a second spring which provides the head with a natural frequency of movement relative to the intermediate support. This natural frequency of movement is substantially greater than the natural frequency of the centrifugal movement of the intermediate support relative to the primary support. As a result the rotation of the primary support at operating speed causes the intermediate support to move against the bias of the first spring so as to place the head against the tape, while *he head can move rapidly relative to the intermediate support so as to follow high frequency vibration of the tape and to reduce hunching of the tape at the locations where the head first contact it.
