A magnetic transducer arrangement comprises a magnetic core (10), including two poles (12, 14) having a nonmagnetic gap between them, and a body (20) of magnetic material which is located magnetically proximate each of said record medium (24) and said gap. The magnetic core and body of magnetic material together defining a magnetic flux path. A means (36) is provided for generating a control flux which flows in the magnetic flux path in said body of magnetic material. The control flux defines a first region having a relatively low flux defining a first region having a relatively low magnitude of control flux in said body adjacent said gap and at least one region having a higher magnitude of control flux in said body adjacent said gap. The first region is defined in said body to couple information flux between said record medium and said body. A signal winding (30) detects detecting changes in the reluctance of said flux path caused by information flux coupled into said first region of said body from said record medium. <IMAGE> |
