摘要： For a tape contact face to be formed in a thin-film magnetic head having at least one transducing element, by removing material, a reference plane (29) corresponding to the tape contact face is detected by means of a plurality of markers (27A-27J) juxtaposed in a layer and extending transversely to the tape contact face, which markers have first end portions (27A1-27J1) pointing in one direction and second, spatially separated end portions (27A2-27J2) pointing in an opposite direction, with the second end portions located at different distances from the reference plane, inclined with respect to the reference plane, and adjoining each other steplessly.

摘要： Elongate magneto-resistive elements (3) spaced apart on a substrate (9) incorporated in a magnetic circuit constituted by a magnetic yoke (5, 7, 9) which is provided with pole faces (19, 21) for the purpose of co-operating with the registration medium, while each magneto-resistive element is provided with two contacts (3A) for connection to a measuring current source. To improve the stability of the magneto-resistive elements, the magnetic head has strip-shaped coupling elements (17) which magnetically couple the magneto-resistive elements and keep them electrically separated from each other.

摘要： Apparatus for recharging a battery, comprising a compartment which holds the battery so that its electrical terminals are in contact with a pair of electrodes. The electrodes are connectable to the poles of a controllable source of electrical energy. In the compartment a ferromagnetic body is positioned so as to be subjected to mechanical stress in response to mechanical deformation of the battery. An electrical device monitors the magnetic permeability .mu. of the ferromagnetic body by measuring the self-inductance of a coil surrounding at least a portion of the ferromagnetic body. The .mu. of the ferromagnetic body changes by magnetostrictive effects arising from mechanical stress of the ferromagnetic body in response to mechanical deformation of the battery (5) during charging. Expansion of the battery can be used as an indicator that charging has been completed, and that the battery should be disconnected from the source of electrical energy.

摘要： Method of manufacturing a magnetoresistive magnetic head in which a first insulation layer (5) of a non-magnetic material is formed on a support face (3a), on which insulation layer a soft-magnetic layer having an upper face remote from the first insulation layer is formed by deposition of a soft-magnetic material. Subsequently a layer portion is removed for forming the flux-guiding elements (17a, 17b) and an aperture extending between said elements, and non-magnetic material for forming a second insulation layer (18) having an upper face remote from the soft-magnetic layer is deposited on the soft-magnetic layer and in the aperture formed therein, which second insulation layer has such a thickness that, viewed in a direction transverse to the support face, the smallest distance between the support face and the upper face of the second insulation layer is larger than the largest distance between the support face and the upper face of the soft-magnetic layer. Subsequently, a mechanochemical polishing treatment is performed as from the upper face of the second insulation layer for forming a main surface (19) at which magnetoresistive material is subsequently deposited for forming a magnetoresistive element (23).

摘要： A magnetic head for reading analogue information on a track of a recording medium associated with the magnetic head. The head has a strip of magnetoresistive material serving as a reading element and arranged in a magnetic yoke at a given distance from the pole faces formed by the ends of the limbs of the magnetic yoke, the strip being connected in the magnetic circuit formed by the magnetic yoke. The magnetic yoke comprises three limbs separated by non-magnetic layers. The pole face of one of the outer limbs is located at a greater distance from the recording medium than the pole faces of the central limb and the other outer limb.
