摘要:
A magnetic recording head includes a write pole having alternating layers of Fe and Co and a return pole magnetically coupled to the write pole. The layers of Fe may have a thickness from about 1.0 angstroms to about 40.0 angstroms and the layers of Co may have a thickness from about 1.0 angstroms to about 20.0 angstroms. The write pole may have a saturation magnetization greater than about 2.45 Tesla. A method for forming a write pole for a magnetic recording head is also disclosed.

A perpendicular magnetic recording head includes a multilayered main write pole. The main write pole includes a first layer of material, a second layer of material, and an interlayer positioned between the first layer of material and the second layer of material. The second layer of material has a saturation magnetic moment greater than a saturation magnetic moment of the first layer of material.

A grader especially adapted for use in association with a tractor having a three-point hitch with the grader being capable of use in cutting, moving, spreading and leveling all types of soil, aggregate and the like. The grader can also be used to carry, spread and level hot and cold asphalt, soil, aggregate and the like. The grader has blades adjustable to a predetermined depth with the specific angle of the grader blades and the speed of movement in relation to the surface being worked determining the operational characteristics of the grader. The grader includes a pair of transversely extending blades oriented at a particular angle and being vertically adjustably attached to a pair of side frame members having ground engaging slide shoes along the lower surface thereof. The ends of the blades are vertically adjustably connected to the side frame members and provided with manually operated cam structures to adjust the blades vertically. The blades are mounted on an angled support bar in vertically adjusted positions to enable the position of the blades to be adjusted to compensate for wear.

The magnetoresistive sensor has an MR stack and side shields formed by contacts and/or pedestals on either side of the MR stack. The materials for the contacts and pedestals are selected to be magnetically soft, electrically conductive and have a low AMR signal. The contacts and pedestals are magnetically decoupled from the hard bias materials by placement of spacers.

A write pole for a magnetic recording head, such as a perpendicular magnetic recording head, includes a first layer of material adjacent a second layer of material. In one embodiment, the first layer of material has a saturation magnetic moment less than about 1.0 T and the second layer of material has a saturation magnetic moment greater than the saturation magnetic moment of the first layer of material. The first layer of material may include (NiFe)100−yXy, wherein X comprises Cr, Cu and/or Ti and wherein y is in the range of about 2 to about 50.

A perpendicular magnetic recording head includes a laminated main write pole and a return pole magnetically coupled to the main write pole. The main write pole includes a first magnetic layer having a high saturation magnetization, a second magnetic layer having a high saturation magnetization, and a non-magnetic interlayer positioned between the first magnetic layer and the second magnetic layer. The first and second magnetic layers may comprise, for example, FexCoy, wherein 40≦x≦90 and 10≦y≦60.
