<p>Apparatus and method for coupling magnetic flux defining information between a first body of magnetic material (5) and a second body of magnetic material (2) having a magnetic flux path (259) therein. A third body of magnetic material (8) having a transducing zone (9) is included and disposed to be magnetically proximate the first body of magnetic material to couple flux to or from the same, and to have a portion thereof magnetically proximate the magnetic flux path within the second body of magnetic material to provide coupling of flux to or from such flux path. The transducing zone may be controlled for movement across the third body. In specific embodiments described, the first body of magnetic material is a magnetic storage medium (253) such as a layer of hard magnetic material (95) of a tape, and the second body of material is a transducer core (2) of a soft magnetic material.</p> |
