摘要： A magnetic device includes a write element having a write element tip that defines a medium confronting surface. The write element is operable to generate a first field at the medium confronting surface. A conductor is proximate the write element tip and first and second conductive leads are connected to the conductor and configured to deliver a current to the conductor to generate a second field that augments the first field. First and second side elements are disposed on opposite sides of the write element tip in a cross-track direction at the medium confronting surface. At least a portion of the first conductive lead is disposed adjacent the first side element on a side opposite the medium confronting surface, and at least a portion of the second conductive lead is disposed adjacent the second side element on a side opposite the medium confronting surface.

摘要： A magnetoresistive (MR) sensor having reduced operating temperature is disclosed. The MR sensor, which includes an MR stack having a magnetoresistive layer, is configured to operate in a current-perpendicular-to-plane (CPP) mode wherein a sense current flows substantially perpendicular to a longitudinal plane of the magnetoresistive layer. The MR sensor further includes a thermal sink layer positioned with respect to the MR stack to reduce an operating temperature of the magnetoresistive sensor. The thermal sink layer is made of a material having high thermal conductivity, and is preferably separated from the MR stack by a metallic cap or seed layer.
