ABSTRACT:
A rotating transducing head drum that mounts a number of transducer heads for sweeping rotation across the surface of a record medium. The head mounts are either of the bimorph, i.e., laterally displaceable leaf type, or of a non-displaceable leaf type simulating the displaceable type; in either case the mounts are factory secured in substantially identical shoes and in precise predetermined dimensional relation to radially, axially and circumferentially facing gauge surfaces of the shoes. Mating gauge surfaces are factory formed on the drum. Thus, the heads with their shoes are interchangeable in the field without the need for field adjustments.
