    Abstract: An apparatus has a main pole layer of magnetic material, a second layer of magnetic material, a first gap layer of non-magnetic material between the main pole layer and the second layer of magnetic material, and a second gap layer of non-magnetic material disposed between the main pole layer and the second layer of magnetic material. The second gap layer of non-magnetic material can be directly adjacent to the second layer of magnetic material. In accordance with one embodiment, this allows the gap to serve as a non-magnetic seed for the second layer of magnetic material. A method of manufacturing such a device is also described.

    Abstract: 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.

    Abstract: A magnetic recording head is provided including a body with a trailing surface, a plurality of bond pads in a row, each of which is spaced by a gap from an adjacent bond pad along a width of the trailing surface. Each bond pad includes a base layer having a top surface, a coating layer covering at least a portion of the top surface of the base layer, two side edges spaced from each other across a width of the bond pad, wherein a width of the gap between adjacent bond pads is defined by one side edge of each of two adjacent bond pads, a top edge extending between the two side edges, and at least one solder dam comprising a nonwettable, electrically conductive material positioned adjacent to the top edge of at least one of the bond pads.
