Abstract: A tape write transducer includes a first yoke member, a second yoke member and a shield member arranged in a row so that row includes two gaps: an inter-yoke-member gap (between the two yoke members), and a shield-member gap (between one of the yoke members and the shield member). In operations using an underlayerless tape, the magnetic field in the inter-yoke member gap causes magnetic transitions to be written to the underlayerless recording medium in a point along the tape that is in vicinity to the inter-yoke-member gap. In operations using an underlayer tape, the magnetic field in the shield-member gap causes magnetic transitions to be written to the underlayer tape recording layer at a point along the tape that is in vicinity to the shield-member gap.

Abstract: A slide rail assembly includes first and second rails. The second rail, slidable relative to the first rail, has a mounting hole. A connecting device includes first and second units, an engaging element, and an adjusting element. The second unit has a transverse guiding portion located at its counterpart of the first unit. The engaging element, connected to the second unit, has an engaging portion partially located in the mounting hole to connect the connecting device to the second rail. The adjusting element is connected to both units. The second unit is displaceable in response to rotation of the adjusting element, thereby enabling displacement of the engaging portion relative to the mounting hole.

Abstract: A method for forming a magnetic write pole with a trapezoidal cross-section is described. The method consists of first forming a magnetic seedlayer on a base followed by depositing a removable material layer on the seedlayer, and then a resist layer on the removable material layer. A trench is then formed in the resist, and the resist is heated to cause the cross -sectional profile of the trench to assume a trapezoidal shape. The resist is then capped with another resist layer and further heated to cause the width of the trapezoidal trench to become narrower. The cap layer and removable material layer at the bottom of the trench are then removed and the trench filled with magnetic material by electroplating. The resist and seedlayer external to the trench are finally removed to form a write pole with a trapezoidal cross-section.

Abstract: A method of manufacturing a perpendicular magnetic recording head capable of easily and accurately forming a main magnetic-pole layer having a shape suitable for concentrating a magnetic flux is provided. A nonmagnetic layer having a recessed section (a first recessed section and a second recessed section) is formed, and then an additional nonmagnetic layer is formed on an inner surface of the recessed section. Then, a magnetic layer is formed in the recessed section formed with the additional nonmagnetic layer, and then the magnetic layer is cut to form an air bearing surface, so as to form the main magnetic-pole layer.

Abstract: A method for manufacturing a magnetic write head having a write pole with a tapered leading edge and a tapered trailing edge. The method includes forming a non-magnetic bump player over a surface, forming a mask over the non-magnetic bump layer and performing a first ion milling to form a tapered back edge on the non-magnetic bump layer. A magnetic write pole material is then deposited over the surface and over the non-magnetic bump layer. Then a non-magnetic step structure is formed over the magnetic write pole material and an ion milling is performed to form a taper on the upper surface of the write pole. The write pole lateral dimensions can then be defined, and a non-magnetic bump formed over the tapered portion of the upper surface of the write pole. Another ion milling can then be performed to extend the taper of the surface of the write pole.

Abstract: A method of manufacturing the magnetic head includes the steps of: forming the pole-layer-encasing layer; forming an initial nonmagnetic layer in the groove of the pole-layer-encasing layer by physical vapor deposition, the initial nonmagnetic layer being intended to become the nonmagnetic layer later by undergoing etching of a surface thereof; etching the surface of the initial nonmagnetic layer by dry etching so that the initial nonmagnetic layer becomes the nonmagnetic layer; and forming the pole layer in the pole-layer-encasing section formed by the nonmagnetic layer.

Abstract: A method for manufacturing a magnetic write head having a stepped trailing shield. The stepped trailing shield is formed by forming a non-magnetic bump over a write pole prior to electroplating a wrap-around magnetic shield. The method allows the location of the front edge of the bump relative to the back edge of the wrap-around shield to be monitored by measuring the electrical resistance of an electrical lapping guide formed concurrently with these features. This concurrent formation of a lapping guide can be used to define the relative location of other features as well, such as the location of a back edge of a wrap-around shield relative to a flare point of a write pole.

Abstract: A method for manufacturing a magnetic write head having a write pole with a flared step feature that defines a secondary flare point. The method involves depositing a magnetic write pole material on a substrate and then depositing a magnetic material over the write pole material followed by a non-magnetic material. A first mask is formed having a front edge to define the location of the secondary flare point, and one or more material removal processes are used to remove portions of the magnetic layer and non-magnetic layer that are not protected by this first mask. The first mask is replaced by a second mask that is configured to define a write pole, and an ion milling is performed to define the write pole. Shadowing from the magnetic layer and non-magnetic layer form a flared secondary flare point.

In one embodiment, a width LW of a lower magnetic pole piece protuberance of a leading side magnetic pole piece, at a face in contact with a write gap layer, is made smaller than a width TW of an upper magnetic pole piece front layer of a trailing side magnetic pole piece, at a face in contact with the write gap layer, and the width of the lower magnetic pole piece protuberance adjacent to the write gap layer is made larger, in a direction from the write gap layer.

Abstract: A magnetic write head structure that maximizes write field strength while minimizing stray fields. The write pole structure maximizes write field strength by minimizing saturation of the magnetic pole tips, and minimizes stray field writing by preventing magnetic fields from extending laterally from the sides of the magnetic pole. The write head structure includes a write pole having a pole tip configured with a stair notched shape and a steep shouldered base beneath the stair notched portion. This configuration maximizes the amount of flux that can be delivered to the pole tip while also avoiding stray fields. The magnetic pole can also be configured with wing shaped extensions that extend laterally from the pole tip region but which are recessed from the ABS by a desired amount.

Abstract: A magnetic write head and method of manufacture thereof that has a first pole structure having a notched structure configured with a steep shoulder portion and a narrow vertical notch portion extending from the top of the steep shoulder portion. The write head also includes a second pole structure (P2) that has a very narrow width (track width) and that is self aligned with the narrow vertical notch structure of the first pole structure. The write head provides excellent magnetic properties including a very narrow track width and minimal side writing, while avoiding magnetic saturation of the poles.
