Abstract
Apparatus is described for coupling magnetic flux defining information between a first body of magnetic material and a second body of magnetic material having a magnetic flux path therein. A third body of magnetic material having a transducing zone 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 provided coupling of flux to or from such flux path. In specific embodiments described, the first body of magnetic material is a magnetic storage medium such as a layer of hard magnetic material of a tape, and the second body of material is a transducer core of a soft magnetic material.
