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.

摘要： A magnetic head (1) for reading information comprises a magnetoresistive element (21) which is arranged between two flux guides (7, 9) present on a support and is partly located on thinner ends (25, 27) of the flux guides. The flux guides are composed of a basic layer (13, 15) and a main layer (17, 19) which partly covers the basic layer. Subsequently the magnetoresistive element is partly provided on the parts (25, 27) of the basic layer which have been left free by the main layer so that the magnetoresistive element is magnetically coupled to the flux guides via coupling parts (20, 22).

摘要： With a thin-film magnetic head (20) having a flux conductor (21) and a magneto-resistance element (28) the flux conductor is divided into a plurality of flux conductor portions (23) which are spaced apart along the length (25) by a distance (27). This accomplishes a decrease in the mechanical tensions in the flux conductor (21) as a result of which a signal to be read is distorted to a lesser extent.

摘要： A magnetostrictive stress sensor is provided with a soft-ferromagnetic body having a grain structure, at least a part of the grains having a grain size in the transition region between the one-domain and the two-domain state. At this grain size, which is of the order of 1 to 9 &mgr;m for a ferrite body, a relatively large magnetostrictive effect occurs. In a practical embodiment, the ferromagnetic body is formed by a ferrite core, in particular a ferrite ring, around at least a part of which an electric oil is wound, which is incorporated in a measuring circuit for measuring changes in the self-induction of the coil under the influence of mechanical pressure exerted on the ferrite core.

摘要： A read head arrangement comprising n first read heads (h.sub.a.1, . . . , h.sub.a.n) and n second read heads (h.sub.b.1, . . . , h.sub.b.n) of the magnetoresistance type, n transistors (Tr.sub.1, . . . , Tr.sub.n) and switching means (S), where n is an integer greater than two. The first main electrode (collector) of a transistor (Tr.sub.i) is coupled to an i-th output (U.sub.i) of the arrangement. The second main electrode (emitter) of the transistor (Tr.sub.i) is coupled to a first terminal (t.sub.1) of a first read head (h.sub.a.i) and a second read head (h.sub.b.i). The second terminal (t.sub.2) of the first read head (h.sub.a.1) is coupled to a first terminal (a) of the switching means (S). The second terminal (t.sub.2) of the second read head (h.sub.b.1) is coupled to a second terminal (b) of the switching means (S), of which a third terminal (c) is coupled to a point of constant potential (earth), while i ranges from 1 to n.

摘要： A thin-film magnetic head comprises a magnetic yoke, having a first and a second flux conductor (1, 2) and a magneto-resistance element (4) remote from a head face (7). A first edge portion (4a) of the magneto-resistance element (4) is located closer to the head face (7) than a second edge portion (4b). The first flux condutor (1) extends from the head face (7) to close to the first edge portion (4a) and the second flux conductor (2) extends from the head face at least to the second edge portion (4b). Furthermore, the magnetic head includes a further magneto-resistance element (5) which forms part of the magnetic yoke and is located between the first and the second flux conductors (1, 2) at the head face (7).
