摘要： A magnetic field sensor comprises: a magnetic field detecting element that detects magnitude of an external magnetic field based on electric resistance of the magnetic field detecting element to sense current, the electric resistance being varied in accordance with the external magnetic field; an upper shield layer that is formed to cover the magnetic field detecting element; and a protective layer that is formed above the upper shield layer with respect to a direction of stacking. The upper shield layer includes a first portion at least part of which covers a top surface of the magnetic field detecting element, and a second portion that covers the first portion, and, the first portion has a larger absolute value of magnetostriction than the second portion.

摘要： A recording element supported by a slider includes a non-magnetic film and a magnetic pole film. The non-magnetic film has a depression whose inner surface is provided with an amorphous electrode film used as a plating seed film. Above the electrode film, the magnetic pole film is grown by plating. The magnetic pole film may be either an electroplated film grown on the electrode film to have a maximum crystal grain size of 20 nm or less or an electroless plated film. This decreases coercive force of the magnetic pole film.

摘要： The present invention relates to a thin-film device including a thin-film element and a lead conductor film. The thin-film element and the lead conductor film are embedded in an insulating film. The lead conductor film has a terminal area at one end thereof, is connected to the thin-film element at the other end thereof, and between the one end and the other end, has an increased surface area portion whose volume is partially occupied by an insulating material to increase surface area. As a result, there is provided a high frequency thin-film device capable of reducing loss and heat generation due to skin effect, particularly a thin-film magnetic head.
