Abstract: A magnetic transducer head wherein confronting surfaces of a pair of magnetic core parts comprised of a ferromagnetic oxide material are notched, and the notch defining surfaces have metallic ferromagnetic layers supported thereby. The method of physical vapor deposition as known per se is used for forming these layers. The transducer coupling gap of each magnetic head is defined by an aligned pair of pole piece layers formed from the deposited metallic ferromagnetic material. The pole piece layers are inclined at a preset angle with respect to the plane of the coupling gap, and have extensions formed of the deposited metallic ferromagnetic material presenting bend contours between the pole piece layers and the lateral sides of the core parts.

Abstract: It has been found that, if a (negative) bias is applied to a substrate during the sputtering thereto of Alfesil, selective re-sputtering from the substrate film of aluminum and silicon will leave that film rich in iron and, attendantly, of higher saturation magnetization (17,000 gauss) than the starting material Alfesil (10,000 gauss). Such being the case, the invention provides that the sputtering of Alfesil-type material during the manufacture of a magnetic head be performed in two phases, first, while applying a bias of a first sense to a substrate to be sputtered upon, and, second, while applying a bias of different sense (e.g. a zero bias) to the substrate, thereby to cause a composite thin film to be formed on the substrate. The composition of the thin film in question is: 1. a (generally thin) region of material of high saturation magnetization layered with 2. a (generally thicker) region of lesser saturation magnetization.

Abstract: A dual element magnetic transducer in which the thin film MR read element is transversely biased by flux in the air gap of the inductive write core generated by a bias current supplied to the write winding. Flux in the air gap biases the MR element because different integral portions of the MR element have a different spatial relationship to parallel opposing portions of the inductive core. The flux which would normally pass through the gap substantially normal to the sides of the core defining the gap now tends to follow the MR element along a direction normal or transverse to the media to a point where the distance between the MR element and the core is smaller than where it entered. By appropriate control of the bias current and the spatial relationships, a relatively efficient, simple to manufacture dual element magnetic transducer is provided.

Abstract: A magnetic transducer assembly having separate core portions with keyways provided therein. The core portions are assembled to form a substantially closed magnetic circuit defining a transducing gap. The keyways form recesses which are contiguous with a transducer inner space provided by the assembled cores. The inner space and recesses are filled with a non-magnetic bonding material. The resulting bond improves the mechanical coupling between the core portions.

Abstract: A magnetoresistant transducer for reading data present on the tracks of a multitrack magnetic carrier, comprises at least one magnetoresistant element perpendicular to the direction of travel of the data, and first and second magnetic screening means situated at either side of the element.The magnetoresistant transducer comprises deflecting means for deflecting the magnetic field generated by the current flowing through the element. The deflecting means are situated between the latter and the first and second screening means to intercept and deflect the magnetic field lines transmitted by the data items on the track. The deflecting means includes a plurality of mutually parallel thin magnetic blades separated from each other by thin non-magnetic laminations the thickness of which is such that the magnetic coupling between two adjacent laminations is weak. The laminations and magnetoresistances are of anisotropic material and have their axes of easy and difficult magnetization parallel to each other.
