摘要： Embodiments of the present invention help to provide a method for manufacturing a perpendicular magnetic recording head including a main magnetic pole having a width that does not generally vary. According to one embodiment, a magnetic film, a first inorganic mask film, an organic film, a second inorganic mask film, and a resist pattern are formed in this order. Reactive ion etching (RIE) is performed using the resist pattern as a mask to etch the second inorganic mask film and the organic film and form a mask for the subsequent step. A flow rate of an Ar gas is then controlled, and ion milling is performed, to correct a difference between the width of the mask located at the central portion of the wafer and the width of the mask located at the outer peripheral portion of the wafer. The magnetic film is processed to have a uniform track width. Ion milling is then performed to form the main magnetic pole having an inverted trapezoidal shape.

摘要： A head-slider. The head-slider includes a slider, and a thin-film magnetic-recording head. The thin-film magnetic-recording head includes: a read element; a write element; a non-magnetic insulating protective layer disposed around both read and write elements; a resist disposed at a position further away from an air-bearing surface than the read element; and, a hard-material member including a material selected from the group consisting of silicon carbide and tungsten, which is disposed at a position further away from the air-bearing surface than the read element and the write element. Both an end of the resist and an end of the hard-material member overlap the write element when viewed in a stacking direction. A ratio of a distance from the air-bearing surface to a deepest end of the hard-material member to a distance from the air-bearing surface to a deepest end of the resist is at least 0.9.

摘要： Embodiments of the present invention provide a perpendicular magnetic recording head suitable for high density recording that suppresses erasure after recording by reducing the remanent magnetization Mr of the main magnetic pole and thereby decreasing the squareness S. Accordingly to one embodiment, a main magnetic pole piece of a perpendicular magnetic recording head includes a FeCo ferromagnetic layer, into which a NiFe soft magnetic layer is inserted. Inserting the NiFe soft magnetic layer in a position in the FeCo ferromagnetic layer 1 to 7 mm away from a nonmagnetic layer allows a remanent magnetization Mr to be decreased without changing the number of layers of the nonmagnetic layer or a film thickness of the FeCo ferromagnetic layer. This helps suppress erasure after recording.

摘要： Disclosed is a magnetic disk apparatus including a magnetic reproducing head portion, and a magnetic recording head including an upper magnetic core having a end portion and a rear portion. As a resist for a frame which is used for forming the rear portion, a negative resist or an electron beam resist is used, whereby the frame is formed without any adverse effect of halation from a coil insulating film. That is, it is possible to manufacture a magnetic recording head in which the rear portion of an upper magnetic core is not emerged at the face opposed to a medium, and hence to obtain a magnetic disk apparatus exhibiting an areal recording density of 5 Gbit/in2 or more by mounting a magnetic recording/reproducing head including such a magnetic recording head.

摘要： A magnetic head for perpendicular recording without writing from the lateral sides of a main pole and without erasing data on adjacent tracks. A magnetic disk storage apparatus using the magnetic head. The lateral side of the main pole of a magnetic head for perpendicular recording may have an inverted tapered shape obtained by forming a groove as a track portion to an inorganic insulating layer and then forming a magnetic layer and then flattening the upper surface. A leading edge, a trailing edge, or both lateral edges of the magnetic head may be tapered. The taper may be either smooth and linear or curved in profile.
