Magnetic head having a thermal fly-height control (TFC) structure under a flat lower shield

摘要

In one embodiment, a method includes forming a conducting material above an insulating film, applying a mask to portions of the conducting material in a shape of a TFC structure, removing exposed portions of the conducting material to form the TFC structure, depositing an insulating film above the TFC structure, and planarizing the insulating film to form a planar upper surface of the insulating film. In another embodiment, a magnetic head includes a TFC structure positioned between insulating films and a magnetic element positioned above the TFC structure, the TFC structure configured for providing localized thermal protrusion of the magnetic head on a media facing surface thereof, wherein an upper surface of an upper of the insulating films is planar, the magnetic element includes at least one of a main magnetic pole and a read sensor, and the TFC structure is configured for providing thermal protrusion of the magnetic element.

1. A magnetic head, comprising:
a thermal fly-height control (TFC) structure positioned between insulating films, the TFC structure configured for providing localized thermal protrusion of the magnetic head on a media facing surface thereof, wherein an upper surface of an upper of the insulating films is planar; a main magnetic pole positioned above the TFC structure, the main magnetic pole being configured for writing data to a magnetic medium, wherein the TFC structure is configured for providing thermal protrusion of at least the main magnetic pole; a stitch pole positioned above the TFC structure and below the main magnetic pole, wherein the main magnetic pole is coupled to the stitch pole; and a trailing shield positioned above the main magnetic pole on the media facing surface of the magnetic head, wherein an end of the TFC structure farthest from the media facing surface of the magnetic head extends beyond an end of the stitch pole farthest from the media facing surface of the magnetic head.
