摘要: A thin film magnetic head comprises a lower magnetic member and an upper magnetic film which constitute a magnetic circuit having a magnetic gap at a predetermined location, and a conductor film forming a coil which intersects the magnetic circuit. At least the upper magnetic film has a magnetostriction constant which is not greater than 6.times.10.sup.-7 in the absolute value.

摘要: A thin film magnetic head comprises an upper magnetic film and a lower magnetic film which cooperate to constitute a magnetic circuit including a magnetic gap, and a coil conductor film constituting a coil having a predetermined number of turns and extending between the upper and the lower magnetic films to intersect the magnetic circuit. The upper magnetic film is composed of a laminate constituted by magnetic thin film layers and non-magnetic thin film layers stacked alternately with each other. An electrically insulating layer formed of a photo-sensitive resin is interposed between the upper magnetic film and the coil conductor film.

摘要: A method of patterning a thin film by dry etching is disclosed in which, in order for a thin alumina film to have a predetermined pattern, the thin alumina film is selectively removed by carrying out the ion beam etching which uses a carbon fluoride gas, while using a photoresist film as a mask.
