Abstract: A bond pad set includes at least one ground pad and at least one electrical bond pad configured to bias and send/receive signals. The bond pad set is electrically connected to a multiplicity of electrical components. At least one electrical bond pad of the bond pad set is shared between two or more of the electrical components.

Abstract: A read head with at least two separately addressable read transducers that are coplanar in a cross track direction. The read transducers have a cross track width, wr, and a center-to-center separation distance between the two read transducers either greater than 3wr or the distance of two tracks of an associated medium in the cross track direction.

Abstract: An apparatus such as a magnetic recording head with at least two separately addressable read transducers that are coplanar in a cross track direction. The apparatus includes first coplanar electrical contacts respectively disposed on and in electrical contact with first surfaces of the at least two read transducers and an electrically insulating magnetic material disposed between the electrical contacts.

Abstract: In an example, a method of manufacturing a transducer head comprises configuring a control circuit to actively synchronize magnetic responses of a shield and a write pole during operation. The method also comprises configuring the control circuit to energize at least one coil wire during operation with a current direction opposite to current flow in a main transducer head coil. In another example, a method comprises actively synchronizing magnetic responses of a shield and a write pole. In another example, a transducer head comprises a write pole and a shield, and a control circuit actively synchronizes magnetic responses of the shield and the write pole.

Abstract: A writer includes a leading edge, a trailing edge, a longitudinal axis defined between the leading and trailing edges, and a transverse axis orthogonal to the longitudinal axis. A writer region is provided at a protruded section of the trailing edge oriented along the longitudinal axis. A write pole is arranged at the protruded section to write data to two locations spaced apart from one another relative to the transverse axis for a range of skew angles.

Abstract: A magnetic head having an air bearing surface is used to reduce thermal pole tip protrusion and recession. The magnetic head includes a substrate and a data transducer positioned upon the substrate adjacent the air bearing surface. The data transducer is comprised of a plurality of metallic layers. A compensation structure is positioned adjacent to at least one of the plurality of metallic layers, is exposed at the air bearing surface or recessed at the ABS and extends substantially perpendicular from the air bearing surface. The compensation structure is formed of a material having a coefficient of thermal expansion less than a coefficient of thermal expansion of a material forming the substrate.
