Perpendicular magnetic write head having a current carrying element for in-plane field assisted magnetic recording

A magnetic data storage system, comprising:

• a magnetic medium;
• at least one magnetic head;
• a drive mechanism for passing the magnetic medium over the at least one magnetic head;
• and
• a controller electrically coupled to the at least one magnetic head for controlling operation of the at least one magnetic head,
• wherein the at least one magnetic head comprises:
• a main pole configured to produce a magnetic writing field applied to the magnetic medium at an overall angle with respect to a magnetic anisotropy axis which is in a direction perpendicular to a plane of a surface of the magnetic medium;
• two bundles of carbon nanotubes capable of carrying current substantially positioned longitudinally inline with a down-track direction on either side of the main pole in a cross-track direction near a media facing surface of the main pole, the bundles of carbon nanotubes being configured to produce an assisting magnetic field applied only in a cross-track direction parallel to the plane of the surface of the magnetic medium,
• wherein the overall angle is between about 25° and about 45°,
• an insulator layer positioned between each bundle of carbon nanotubes and the main pole;
• electro-conductive connectors positioned on each longitudinal end of each bundle of carbon nanotubes;
• a trailing shield positioned on a trailing side of the main pole;
• a leading shield positioned on a leading side of the main pole;
• and
• side shields positioned on either side of the main pole in the cross-track direction,
• wherein a portion of the magnetic writing field emanates from edges of the main pole and is applied at an angle to perpendicular to the plane of the surface of the magnetic medium, wherein the angle to perpendicular is between about 10° and about 90°.
