摘要： A thin film magnetic head comprises a lower magnetic shield layer and an upper magnetic shield layer which are mutually opposed in the layering direction, a magnetoresistance effect element having a free layer, and a bias-applying layer which applies a bias magnetic field to the magnetoresistance effect element. The free layer is positioned between the lower magnetic shield layer and the upper magnetic shield layer, and is positioned on the side of the media-opposed surface. The bias-applying layer has a first portion, a second portion, and a third portion. The first portion and the second portion are positioned at a distance in the track width direction so as to enclose the magnetoresistance effect element therebetween. The third portion is positioned either between the magnetoresistance effect element and the lower magnetic shield layer or between the magnetoresistance effect element and the upper magnetic shield layer, and connects the first portion and the second portion.

摘要： A magnetoresistive effect sensor includes a pinned layer, a nonmagnetic spacer layer, and a free layer having a total thickness of at least 10 nm. The sensor has insulating films disposed on both side surfaces of the spin valve film. The sensor has hard magnetic films disposed on the insulating films for applying a biasing magnetic field to the free layer. Each hard magnetic film extends toward the free layer in a vicinity of the spin valve film, such that as each hard magnetic film extends toward the spin valve film, a cross-sectional area thereof in a plane perpendicular to the layer width direction becomes progressively smaller. Each hard magnetic film has, in a plane parallel to the air bearing surface, a first boundary line which at least partially faces the free layer and substantially defines an end point of the hard magnetic film in the layer width direction.

摘要： Provided is a magnetoresistive effect element in which a magneto-sensitive portion is formed in a position where the portion sufficiently receives bias field and the influence of reattachments on reading output is avoided. The magneto-sensitive portion has a pinned layer, a non-magnetic intermediate layer and a free layer. A multilayer, that includes a foundation layer, the magneto-sensitive portion and a cap layer, has upper side surfaces forming an inclination angle θC, intermediate side surfaces forming an inclination angle θS, and lower side surfaces forming an inclination angle θU. The inclination angle θS is greater than both of the inclination angles θC and θU. The boundary between the upper side surface and the intermediate side surface is located above a side surface of the magneto-sensitive portion, and the boundary between the intermediate side surface and the lower side surface is located below a side surface of the magneto-sensitive portion.
