Optimized Dual Thermal Fly-Height Design For Dual Writers For Advanced Magnetic Recording

A magnetic recording head, comprising:

• a first write head comprising a first thermal fly height control element;
• a second write head disposed adjacent to the first write head, the second write head comprising a second thermal fly height control element, wherein the second write head comprises a first read head and a third thermal fly height control element coupled to the first read head;
• and
• means for providing power, as AC current and DC current individually, or AC current and DC current simultaneously, to power one or more of the first thermal fly height element, the second thermal fly height element, and the third thermal fly height element over a common electrical circuit.

A magnetic recording head, comprising:

• a first write head comprising a first main pole and a first thermal fly height element;
• a second write head disposed adjacent to the first write head, the second write head comprising a second main pole, a second thermal fly height element, and a third thermal fly height element, wherein the second thermal fly height element is disposed further away from the second main pole than the third thermal fly height element;
• and
• an electrical circuit configured to providing power, as AC current and DC current individually, or AC current and DC current simultaneously, to power one or more of the first thermal fly height element, the second thermal fly height element, and the third thermal fly height element over a common electrical circuit.
