Abstract
A unique concentric rotary transformer for use in a rotating head tape transport, wherein a length of tape is positioned relative to the rotating head and data is recorded and/or reproduced therefrom, is disclosed. The rotary transformer comprises two assemblies one of which rotates relative to the other and thereby transmits electrical signals. Each assembly includes a ferrite cylindrical core piece with two grooves machined in the core piece. The grooves are axially and circumferentially displaced along a longitudinal axis of said core piece. A continuous coil with two legs, is positioned within the grooves of the core piece whereat mutual inductances generated in the ferrite core by each leg of the coil effectuate signal transfer across the transformer interface.
