Abstract
Rotary transformers are important parts of magnetic tape recorders using cylindrical scanners. Typically, heads for recording and playback are mounted on a rotating cylinder which scans the tape at high speed. Writing and reading signals are coupled to the heads through a rotary transformer. This paper describes a design procedure for a multi‐channel, miniaturized transformer for application to high‐density, digital magnetic tape recording. The requirements for the particular example presented were for the transformer to pass six identical recording/playback channels with a minimum insertion loss. The outside diameter of the transformer should be no greater than 16.5mm.
