摘要： A method of manufacturing a magnetic device for propagating and detecting magnetic domains. At least one thin domain layer of a magnetizable material is provided on a nonmagnetic substrate body and hereon are provided a number of layers of which there are at least a detection layer of magnetoresistive material and a layer of electrically insulating nonmagnetic material. The latter is provided with a propagation layer of magnetizable material in a pattern which satisfies the requirements of propagation of magnetic domains and the requirements of detecting magnetic domains. The non-covered parts of at least the layer of electrically insulating, nonmagnetic material and of the layer of magnetoresistive material are successively removed, each time by means of a method which does not substantially attack the pattern of the material present above the relevant layer.

摘要： Method of manufacturing a thin-film magnetic head provided with a transducing element (23) and at least one flux-guiding element (17a, 17b). An electrically conducting layer (8) of a non-magnetic material and a second electrically insulating layer (9) of a non-magnetic material are successively formed on a first electrically insulating layer (5) of a non-magnetic material. The second electrically insulating layer is subsequently provided with at least an interruption exposing a portion of the electrically conducting layer. Subsequently, the flux-guiding element is formed by electrodepositing a soft-magnetic material on said portion until the interruption is filled, whereby the flux-guiding element and the second electrically insulating layer constitute an at least substantially plane surface on which an electrically insulating spacer layer (21) is formed. Subsequently, the transducing element is provided on the spacer layer. The magnetic head thus formed has a non-magnetic transducing gap (35) terminating in a head face (33) and being constituted by the first electrically insulating layer (5) and the electrically conducting layer (8).

摘要： A method of making inclined sides on a metal pattern which is grown on a substrate by electroplating as a preliminary measure to the coating of the substrate with the metal pattern by an insulating layer. The main deposition of the insulating layer by sputtering is preceded by a sputter-etching step which transforms the rounded edges of the metal pattern into inclined sides.

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).
