摘要： A thin film head of the floating type includes a head slider 1 having a surface to be opposed to the signal face of a recording medium with a small space formed therebetween. At least one head element 2 is formed by thin film forming techniques on a face of the head slider 1 orthogonal to the slider surface. A protective layer 3 is formed over the head slider face and covers the head element 2. The head slider 1 has a pair of side faces orthogonal to the slider surface to be opposed to the medium and extending in parallel to each other respectively at opposite sides of the head element 2. The protective layer 3 is formed at each of its opposite side portions with a bulging-out curved face R smoothly extending from the surface of the protective layer 3 to the side face of the head slider 1.

The core layer 11 consequently formed has a surface including a pair of curved faces R, R smoothly connecting opposite side faces of the layer 11 with respect to the direction of width of a track to the top face of the layer 11, enabling a protective layer forming step to provide a flawless protective layer 14.

摘要： A magneto-resistive head has an upper shield layer, a lower shield layer spaced a distance from the upper shield layer, a magneto-resistive layer disposed over the lower shield layer, a shunt layer disposed adjacent to the magneto-resistive layer for giving a magnetic bias field to the magneto-resistive layer, and a electrode layer in contact with the magneto-resistance device and the shunt layer for providing an electric current to both of the magneto-resistive layer and the shunt layer electric current. The magneto-resistive layer, the shunt layer and the electrode layer are disposed between the upper shield and the lower shield. The shunt layer consist of molybdenum having a grain size more than 150 angstrom. The shunt layer has low specific resistance. Therefore, the thickness of the shunt layer can be reduced. As a result, the distance between the upper and lower shield layer can be reduced. Consequently, the gap length of the magneto-resistive head is narrower than prior art magnetic heads.

摘要： The present invention provides a perpendicular magnetic write head capable of preventing unintended erasure of information due to spread of a magnetic field for writing. A leading shield, two side shields, and a trailing shield are disposed around (a front end portion of) a main magnetic pole layer. A nonmagnetic layer having a uniform thickness formed by ALD is provided between the front end portion and two side shields. Consequently, intervals are constant in any positions. Spread of magnetic fields for recording in a write track width direction is suppressed sufficiently more than the case where the intervals vary among positions.
