摘要： An inductive write head includes a first pole and a second pole that form a yoke having a write gap between the first pole and second pole. The second pole is formed of a particular Co100-a-bZraCrb compound. More specifically, the second pole is formed where “a” is in the range of about 2 atomic percent to about 18 atomic percent, and “b” is in the range of about 0.5 atomic percent to about 6 atomic percent. The magnetic write element also includes a conductive coil which lies between the first pole and the second pole. The inductive write head also includes a first yoke pedestal attached to the first pole, and a second yoke pedestal attached to the second pole, with the write gap formed therebetween. Further, the first yoke pedestal has a pedestal width that defines the write element trackwidth and that is smaller than the pedestal width of the second yoke pedestal.

摘要： The present invention provides a thin film write head having an improved laminated flux carrying structure and method of fabrication. The preferred embodiment provides laminated layers of: high moment magnetic material, and easily aligned high resistivity magnetic material. In the preferred embodiment, the easily aligned laminating layer induces uniaxial anisotropy, by exchange coupling, to improve uniaxial anisotropy in the high moment material. This allows deposition induced uniaxial anisotropy by DC magnetron sputtering and also provides improved post deposition annealing, if desired. It is preferred to laminate FeXN, such as FeRhN, or other crystalline structure material, with an amorphous alloy material, preferably Co based, such as CoZrCr. In the preferred embodiment, upper and lower pole structures may both be laminated as discussed above. Such laminated structures have higher Bs than structures with insulative laminates, and yokes and pole tips and may be integrally formed, if desired, because flux may travel along or across the laminating layers. The preferred embodiment of the present invention improves soft magnetic properties, reduces eddy currents, improves hard axis alignment while not deleteriously affecting the coercivity, permeability, and magnetostriction of the structure, thus allowing for improved high frequency operation.

摘要： A magnetoresistive head having improved overwrite performance and a small trackwidth. The magnetoresistive head having a magnetic yoke formed of first and second poles joined at a back gap region and having an opposite write gap region. A pedestal with a top portion constructed of a high saturation moment material is provided on the first pole, limited to the write gap region and spaced from the read element so as to prevent popcorn noise in read sensor. The high moment pedestal is raised above surrounding structure causing the second pole to define a very low apex angle in the write gap region.

摘要： A preferred embodiment provides a thin film write head having upper and lower pole structures each having pedestal pole tips formed with CoNiFe. The pedestal pole tips may have from about 60% to about 70% Co and from about 10% to about 15% Ni. The upper pole structure of the preferred embodiment has a laminated yoke portion having upper and lower layers. The lower layer is stitched to the pedestal pole tip of the upper pole structure and comprises FeXN, where X is selected from the group consisting of Rh, Ta, Hf, Al, Zr, Ti, Ru, Si, Cr, V, Si, Sr, Nb, Mo, Ru, and Pd. The upper layer comprises NiFe preferably having from about 15% to about 55% of Fe. It is preferred to define the lower layer of the yoke by etching FeXN material using the upper layer as a hard mask. In a preferred method and embodiment, the top surfaces of the conductor coil and the upper pedestal pole tip are planarized with an inorganic capping layer formed thereover to insulate the conductor coil from the yoke and to provide a low apex angle to form the yoke over.

摘要： The present invention relates to a relocation method, system and network element for changing a serving radio resource control entity After an initial operating state in which a user equipment (30) has radio links with a serving network element (20) and a drift network element (21) supporting said serving network element (20) with a wireless connection, the serving network element (20) transmits a relocation-specific information to a target network element (22). Based on the relocation-specific information, the target network element (22) establishes a link to the drift network element (21), such that the drift network element (21) can receive user traffic from both the serving network element (20) and the target network element (20). Then, the radio resource control is relocated to the target network element (20). The relocation-specific information may comprise an identifier or a list of identifiers of drift network elements. Thus, existing soft handover techniques can be enhanced by allowing a user plane connection to be maintained with drift network elements. Thereby, any amount of drift network elements can be kept, with improved radio performance as a consequence.

摘要： A rotary cone rock bit includes one or more hole cleaning nozzles and one or more bit cleaning nozzles. The hole cleaning nozzles of one drill bit define a projected fluid path disposed at a lateral angle of less than six degrees in order to achieve a large impingement pressure on the hole bottom. The bit cleaning nozzles of the same drill bit define a projected fluid path disposed at a lateral angle of at least six degrees in order to pass within 0.5 inches of the teeth on leading edge of the lagging roller cone. This results in a drill bit that both cleans the bottom hole and cleans cone inserts.
