Abstract: A magnetic-field-sensitive device includes several magnetic-field sensors. Each sensor comprises a compound element surrounded by a coil winding. Each compound element is made of two ferromagnetic cell components extending in one axial direction with uniaxial magnetic anisotropy and with different coercive field strengths. A spontaneous reversal of magnetization is produced by an external magnetic switching field only in the cell component having the lower coercive field strength. The magnetic-field sensors are combined to form a series arrangement, or array, and the coil windings and cell components of the magnetic-field sensors of the array are formed as thin-film structures on a non-magnetic substrate.

Abstract: The thin film magnet head is to be guided over a recording medium to be magnetized perpendicularly, in which flux changes are to be registered along a track with a predetermined record wavelength and flux change density. The magnet head contains a flux-carrying, ring head-like guiding element with two magnet legs which constitute magnet poles which are arranged one behind the other and separated by a gap of predetermined width and having predetermined extents in the movement direction. With this magnet head the expanse for signal processing in a write/read channel is to be reduced. The magnet head fulfills this end by at least approximately satisfying the following relation:.lambda.*=g+max(A.sub.1, A.sub.2).lambda.* being the record wavelength which results for the value D.sub.p of the flux change density at which the read voltage of the magnet head is maximum; g, the width of the gap; and max(A.sub.1, A.sub.2) the greater value of the two extents (A.sub.1, A.sub.2) of the magnet poles.

Abstract: Thin-film magnetic head has a layer structure for vertical magnetization. The magnetic head is constructed in thin-film technology and is guided over a recording medium to be magnetized vertically. The head includes a ring core head magnetic guide body with a first and second magnetic shank which form sequentially arranged magnetic poles. The write function is carried out with the first magnetic shank and both magnetic shanks carry out the read function. This magnetic head is constructed so that the concomitant reading of data residues in the margin regions of data tracks is prevented. To this end the magnetic pole of the first magnetic shank has a greater width than the magnetic pole of the second magnetic shank with both magnetic shanks being constructed largely of the same material at least in their end regions bordering on the magnetic poles.

Abstract: A magnetic head having layered structure for a recording medium for vertical magnetization contains a conductor body on a non-magnetic substrate for conducting the magnetic flux with two magnet legs, the end pieces of which form a thin main pole and a comparatively thicker auxiliary pole. The two magnetic poles are separated by an insulating gap layer of at least 5 .mu.m. This magnetic head and particularly its gap layer should be relatively simple to produce. Recesses are provided in the substrate to submerge at least the end piece of the auxiliary pole of one magnet leg and an adjoining part of this leg as well as at least part of the gap layer.

Abstract: A magnetic head comprising a stratified buildup on a non-magnetic substrate for a recording medium to be magnetized vertically comprises a ring head-like conducting body for carrying magnetic flux having two magnet legs which comprise several magnetic layers with predetermined saturation magnetization and delineate a space in between, through which the turns of an at least largely flat write/read coil winding extend. With this head it is possible to generate a sufficiently large read voltage, wherein the same advantages are present as if single-pole heads are used.

Abstract: A magnetic memory comprising a thin-film magnetic head as well as a recording medium which is provided with a storage layer that can be magnetized perpendicularly (vertically). The magnetic head comprises two magnet legs having a magnetic layer each, the magnetic poles of which are arranged in tandem, forming a gap therebetween. With this magnetic head, a write and read function with high efficiency is obtained. It is provided for this purpose that at least one magnetic layer of the trailing magnet leg differs at least in its end region with respect to its magnetic behavior (magnetic resistance; saturation magnetization) from the at least one magnetic layer of the leading magnet leg at least in its end region, and that the coercivity of the material of the storage layer of the recording medium is chosen sufficiently high, so that overwriting of the storage layer of the recording medium by the trailing magnet leg is, at least largely, eliminated.

Abstract: A magnetic thin-film head with layer-wise buildup on a nonmagnetic substrate is provided for a recording medium which can be magnetized perpendicularly (vertically), and contains a conduction body which carries the magnetic flux, and the magnet legs of which form a main and an auxiliary pole. With these magnet legs which are arranged on the substrate with predetermined spacing side by side, a write/read coil winding is associated, the conductor turns of which extend through a space formed between the magnet legs. This magnetic head should be able to fly at a very small flying altitude above the recording and should at the same time be easy to realize in a thin film technique. To this end, it is provided that only the partially overlapping magnet legs serve as the magnetic conduction body, which are connected together in their common overlap zone, forming a magnetic return in a partial region and are spaced outside of this return region, forming the intermediate space for the conductors.

Abstract: A method for manufacturing a magnetic head by a thin-film technique which head comprises at least two magnet legs which have pole surfaces which face a recording medium and which lie in a common plane. With this method, a preliminary product of the magnetic head having end pieces of the legs which extend beyond this plane and which are spaced by a small gap, and an electrically conducting structure are applied in such a manner that this structure is separated, if the substrate body is processed by material removal from the side facing the recording medium, just when the plane of the pole surfaces has been reached, into two conductor parts electrically insulated from each other. With this method, the area portion required for the manufacture of a magnetic head on the substrate body is to be reduced.

The conduction body has two magnet legs, of which the poles facing the recording medium are arranged in tandem as seen in the direction of motion of the head and having a predetermined spacing from each other. An at least largely flat read/write coil winding is provided, the turns of which extend through a space formed between the magnet legs. In this magnetic head, a switchable write/read function with a sufficiently large read voltage is obtainable. In addition to the write/read coil winding, a further coil winding is provided only for executing the write function, the turns of which are at least in part arranged in a region outside of the ring-head-like conduction body.

Abstract: A combined magnetic write and read head for a recording medium to be magnetized perpendicularly comprises a magnetic conductor body for carrying the magnetic flux, the conductor body having two pole legs which are arranged one behind the other in the direction of relative motion of the head and medium and having a predetermined distance from each other. At least one coil winding is associated with the conductor body. In order to reduce problems regarding the mechanical design of such a head and to make possible at the same time a switchable write and read function having high efficiency, a separate coil winding is associated with each pole leg. The flux conduction directions in the pole legs are adjustable for the write function by means of the separate coil windings such that the flux directions extend, at the ends of the pole legs facing the recording medium, parallel at least to a high degree.

With this magnetic head it is possible to generate a magnetic writing field, the field pattern of which has a pronounced largely symmetrical maximum. It is provided that the current conductors of the coil arrangement also run through a further space where the current flow directions in the current conductors arranged on both sides of the central magnet leg are opposed to each other.

With this magnetic head, it is possible to generate a sufficiently high read voltage and to provide a magnetic head wherein the write and read function can be switched. To this end, the conduction body carrying the magnetic flux comprises, besides the ring-head-like head part formed by the two magnet legs, a leg part extending beyond the head part.
