ABSTRACT:
A rotary magnetic head assembly comprises rotatable and stationary cylinders disposed in confronting relation to each other. A rotary transformer is arranged between the cylinders and includes confronting rotatable and stationary transformer cores fixedly mounted respectively to the rotatable and stationary cylinders. An annular supporting member is located at an outer peripheral surface of the stationary transformer core and includes support portions for supporting the stationary transformer core. Signal transmission junction elements are provided on the outer peripheral portion of the supporting member. The outer peripheral portion of the supporting member is provided with bores through which fixing members are inserted to fix the stationary transformer core to the stationary cylinder. The outer peripheral surface of the stationary transformer core is formed to have a non-circular shape so that the outer peripheral portion of the stationary transformer core can rest on the support portions of the supporting member.
