摘要： A write element including a pole tip shield is disclosed In embodiments disclosed, for example, the pole tip shield includes side shield portions fabricated of a graded magnetic moment material to form graded side shield portions having a magnetic moment that decreases in the down-track direction along a length of the side shield portions In another embodiment, the pole tip shield includes side shield portions having a shortened length extending along a partial length of side edges of the pole tip In illustrated embodiments, the side shield portions are formed of a contoured body having an indented portion forward of the leading edge of the pole tip. The indented portion has a rounded indented surface contour forming a rounded profile for a gap region between a leading edge portion of the pole tip shield forward of the leading edge of the pole tip.
摘要翻译：公开了一种包括极尖屏蔽的写入元件。在所公开的实施例中，例如，极尖屏蔽包括由渐变磁矩材料制成的侧屏蔽部分，以形成具有在下轨道方向上减小的磁矩的分级侧屏蔽部分在另一个实施例中，极端护罩包括具有沿着极尖的侧边缘的部分长度延伸的缩短长度的侧屏蔽部分。在所示实施例中，侧屏蔽部分由成形体在极尖的前缘向前具有凹入部分。凹入部分具有圆形的缩进表面轮廓，其形成圆顶轮廓，用于在极尖前缘前方的极尖护罩的前缘部分之间的间隙区域。

摘要： An apparatus comprises a head transducer and a resistive temperature sensor provided on the head transducer. The resistive temperature sensor comprises a first layer comprising a conductive material and having a temperature coefficient of resistance (TCR) and a second layer comprising at least one of a specular layer and a seed layer. A method is disclosed to fabricate such sensor with a laminated thin film structure to achieve a large TCR. The thicknesses of various layers in the laminated thin film are in the range of few to a few tens of nanometers. The combinations of the deliberately optimized multilayer thin film structures and the fabrication of such films at the elevated temperatures are disclosed to obtain the large TCR.
