摘要： A soft-magnetic multilayer thin film produced by electroplating, wherein an anode-dissolution process is effected by intermittently applying a reverse d.c. bias current with respect to the plating-forward current. Involving the anode-dissolution process allows the formation of a re-dissolution effect layer differing in crystal structure from the plated film layer. A soft-magnetic multilayer thin film characterized by having a multilayer film structure which comprises a plated layer and a re-dissolution effect layer laminated to each other and which the plated layer is at least magnetically isolated. Further, a method of manufacturing a soft-magnetic multilayer thin film having a multilayer film structure magnetically isolated only through plating, which is offered by introducing the anode-dissolution process. In a thin-film magnetic head produced by using a soft-magnetic multilayer thin film, the soft-magnetic multilayer thin film serves as at least one of an upper magnetic core layer and a lower magnetic core layer.

摘要： A method of producing a thin film magnetic head in which at least one of two, lower and upper, magnetic layers is formed of a soft magnetic amorphous alloy thin film of a given pattern shape, includes the steps of preparing a soft magnetic thin film to communicate directly or magnetically with the soft magnetic amorphous alloy thin film so that an external magnetic field can effectively be applied, during in-field heat treatment, to the soft magnetic amorphous alloy thin film of the head core assembly from a direction at a right angle to the direction of a head core magnetic path, inducing uniaxial magnetic anisotropy in the soft magnetic amorphous alloy thin film through heat treatment in the external magnetic field, and removing the soft magnetic thin film for application of the external magnetic field during the in-field heat treatment. Also, another form of the method in which at least one of two, lower and upper, magnetic layers is formed by electroplating of a soft magnetic alloy thin film of a given pattern shape, includes the steps of preparing a soft magnetic thin film to communicate directly or magnetically with the soft magnetic electroplated alloy thin film so that an external magnetic field can effectively be applied, during in-field electroplating action, to the soft magnetic electroplated alloy thin film of the head core assembly from a direction at a right angle to the direction of a head core magnetic path.

摘要： The present invention provides a method for forming thin films, wherein thin films with a uniform thickness can be formed on substrates as objects such as spheroids, even when the films are formed by conventional film-formation methods using an incident particle beam coming from a specific direction (e.g., evaporation and sputtering). In the method, thin films are formed on substrates such as spheroids with an incident particle beam coming from a particle source located in a specific direction by performing a spin motion together with a swing motion. The spin motion is a rotation of the substrate at a constant angular velocity about the spheroidal axis. The swing motion is a rotational oscillation of the same substrate for rotationally oscillating the axis at a constant cycle in one surface, where the center of the rotational oscillation is in the vicinity of the midpoint between two focal points on the axis of the spheroid. As a result, thin films with a uniform thickness in both the peripheral direction of the substrate and in the rotational axis direction of the spin motion can be formed even on substrates including spheroids.
