Abstract: A magnetic transducer reads and writes electric signals recorded as tracks of magnetic manifestations on a magnetic medium moving relative to the transducer. The transducer is a high permeability magnetic sheet with a row of apertures along one edge of the sheet and a narrow slot connecting each aperture to the edge. Each aperture and slot corresponds to one track on the medium. An electric wire is threaded through the aperture for external connection. The edge of the sheet is adjacent the medium and at a fixed angle transverse the direction of relative motion. The angle and the thickness of the sheet determine the track width and, together with the total width of the sheet across the medium, the amount of information exchangeable with the medium.
