    摘要： Problems such as thermal pole tip protrusion result from thermal mismatch between the alumina and pole material during the writing process. This, and similar problems due to inadequate heat dissipation, have been overcome by dividing the bottom shield into two pieces both of which sit on top of a non-magnetic heat sink. Heat generated by the coil during writing is transferred to the non-magnetic heat sink whence it gets transferred to the substrate. With this approach, the head not only benefits from less field disturbance due to the small shield but also improves heat dissipation from the additional heat sink

    摘要： A method for forming an abutted junction GMR bottom spin valve sensor in which the free layer has a maximum effective length due to the elimination or minimization of bias layer and conducting lead layer overspreading onto the sensor element and the consequent reduction of current shunting. The overspreading is eliminated by forming a thin dielectric layer on the upper surface of the sensor element. When the biasing and conducting leads are formed on the abutted junction, they overspread onto this layer and the overspread can be removed by an ion-milling process during which the dielectric layer protects the sensor.

    摘要： Aggressive (i.e. tight tolerance) stitching offers several advantages for magnetic write heads but at the cost of some losses during pole trimming. This problem has been overcome by replacing the alumina filler layer, that is used to protect the stitched pole during trimming, with a layer of electroplated material. Because of the superior step coverage associated with the plating method of deposition, pole trimming can then proceed without the introduction of stresses to the stitched pole while it is being trimmed.

    摘要： An inductive-type write head and its method of fabrication are disclosed. The write head has a vertically separated two-element planar coil of reduced resistance which is the result of forming the lower of the two coils with windings of a greater height and substantially larger cross-sectional area than those of the upper coil. The formation of a lower coil with greater height is possible because of a surface planarization that allows separating the coils by an alumina layer of minimal thickness. This method allows the reduction of coil resistance without the necessity of enlarging the head dimensions. The reduced resistance results in lower power consumption and the elimination of pole tip protrusion caused by excessive heating during operation.
