    摘要： A layer configured for use in a magnetic stack has electrical resistivity greater than about 5×10−8 Ωm and thermal conductivity greater than about 1 W/mK. In some arrangements, the magnetic stack includes a substrate with the layer disposed over the substrate, a magnetic recording layer disposed over the layer, and a thermal resist layer disposed between the layer and the magnetic recording layer. In some arrangements, the layer is configured to function as a heat sink and a soft under layer. A system that incorporates the layer can include a magnetic write pole, a near field transducer (NFT) positioned proximate the write pole that radiates energy.

    摘要： An apparatus and associated method for a head gimbal assembly for data transduction in a data storage device with a heat assist laser. Various embodiments of the present invention are generally directed to a slider supporting at least a transducing element on an air bearing surface (ABS) and a laser assembly directly attached to a top side of the slider opposite the ABS. The laser assembly is positioned on the top side with no portion of the laser assembly extending past a longitudinal centerline of the slider.
