An apparatus includes a substrate and a reader deposited on the substrate. A laser is formed on a non-self supporting structure and bonded to the substrate. A plurality of heat sink layers are deposited between the reader and the laser and configured to provide thermal coupling between the substrate and the laser and sink heat away from the laser. A waveguide is deposited proximate the laser. The waveguide is configured to communicate light from the laser to a near-field transducer that directs energy resulting from plasmonic excitation to a recording medium.

Electrostatic discharge protection can be afforded to a data recording head in accordance with various embodiments. A data recording head may consist of a circuit having a preamp ground connected to a ground substrate via a ground trace. The ground trace can consist of a first leg connected to the ground substrate and a second leg with an open connection extending from a dice line.

A glide head with a slider body that has a leading edge, a trailing edge and an air bearing surface is disclosed. The glide head also has an array of thermal proximity sensing elements connected in a bridge circuit that are adjacent both the trailing edge and the air bearing surface, a heating element mounted to the glide body for elevating the temperature of the thermal proximity sensing elements in relation to the temperature of an inspected surface, and a controller coupled to the array of thermal proximity sensing elements. The controller receives signals from the thermal proximity sensing elements, and determines the existence of a surface variation in the inspected surface based upon differences in the signals received from the thermal proximity sensing elements.

A transducing head includes at least three magnetic layers. At least two of these magnetic layers function as shields of a reader portion of the transducing head, and at least one of these magnetic layers functions as a pole of a writer portion of the transducing head. Importantly, at least one of the three magnetic layers is formed of a thin film structure having a first and a second ferromagnetic layer, a nonmagnetic spacer layer, and a bias layer. The spacer layer is positioned between the first and the second ferromagnetic layers. The bias layer is positioned adjacent the first ferromagnetic layer. The second ferromagnetic layer has a thickness-magnetic moment product substantially equal to a thickness-magnetic moment product of the first ferromagnetic layer. An easy axis of the second ferromagnetic layer is substantially parallel to an easy axis of the first ferromagnetic layer.
