ABSTRACT:
A magneto-optic recording system includes a scanning wheel head around which is wound a magneto-optic recording tape in spiral fashion. A first magnetic pole piece surrounds the tape outward of the wheel. A second pole piece extends between an aperture on the wheel opposite the tape to a point proximate the first pole piece and is coupled to source of magnetic flux. A light source is directed from inside the wheel toward the aperture and thus to the tape. The wheel, second pole piece, flux source and light source rotate together relative to the tape to direct a magnetic field to successive points of incidence on the tape.
