Abstract

A rotating head assembly useful for scanning a-moving magnetic medium such as a longitudinal tape, includes a plurality of magnetic transducers 10, 12 that are located at the periphery of a rotary drum supporting structure 14. The transducing gaps 16, 18 of the magnetic transducers are disposed at the outermost edge of the rotating drum for making contact with the moving storage medium. The transducer cores are linked by a winding 20 to an annular transformer core 22 disposed in the center of the drum structure. In turn, the transformer core is coupled to a stationary electrical coil 26 passing through an aperture in the drum. The stationary coil provides signal leads for channeling input or output signals to and from the magnetic transducers, respectively.
