摘要： A magnetic head is configured by forming a thin-film-shaped magnetic element on top of a thin film that is provided parallel to a medium-facing surface. An aperture is formed in the thin film, and part of a main magnetic pole is formed to have a tip portion that protrudes into that aperture. This configuration makes it possible to impose highly accurate control over the amount by which thin-film-shaped magnetic elements are recessed from the medium-facing surface, while simultaneously exerting accurate control over the amount of protrusion of the main magnetic pole tip portion by making the thickness of the thin film extremely small. As a result, the recording flux strength at the main magnetic pole tip portion can be increased to the ultimate value thereof, making it possible to supply a head that can record on a high retention force medium suitable for higher densities.

摘要： When manufacturing a thin film magnetic head in which an upper magnetic pole is formed on a lower magnetic pole through a magnetic gap, firstly, at least on the lower magnetic pole, a convex portion possessing the width equivalent to a track width is formed. The convex portion forms a lower magnetic pole tip. Conforming to a contour of the convex shape of the lower magnetic pole, a non-magnetic material layer is formed. A flattening layer is formed on the non-magnetic material layer. The non-magnetic layer is etched with the flattening layer, for example, as a mask. In the non-magnetic material layer, a concave portion self-aligned to the lower portion magnetic pole top (convex portion) is formed. Inside the concave portion, a magnetic layer (upper magnetic pole tip) destined to be a part of the upper magnetic pole is formed. As to the lower magnetic pole tip and the upper magnetic pole tip, the widths of surfaces opposite to the magnetic gap are almost equal, and the central positions thereof almost overlap each other. Thus, a narrow track head structure with high accuracy can be obtained.
