Abstract
Systems and methods for providing a write pole pedestal for microwave assisted magnetic recording systems are provided. One such system includes a magnetic transducer for microwave assisted magnetic recording, the magnetic transducer including a pole including a leading edge and a trailing edge, a trailing shield positioned closer to the pole trailing edge than the pole leading edge, and an energy transducer positioned between the pole trailing edge and the trailing shield, where a trailing parallel side of the trapezoid is smaller than a leading parallel side of the trapezoid.
Claims23
A magnetic transducer for microwave assisted magnetic recording, the magnetic transducer comprising:
- a pole comprising a leading edge and a trailing edge;
- a trailing shield positioned closer to the pole trailing edge than the pole leading edge;
- and
- an energy transducer positioned between the pole trailing edge and the trailing shield,
- wherein a shape of the pole at the trailing edge comprises a trapezoid, wherein a trailing parallel side of the trapezoid is smaller than a leading parallel side of the trapezoid.
A method for fabricating a magnetic transducer for microwave assisted magnetic recording, the method comprising:
- depositing a ferromagnetic material for a pole;
- planarizing the pole material and thereby forming a pole having a leading edge and a trailing edge;
- depositing one or more materials on the planarized pole material to form an energy transducer;
- shaping the energy transducer materials such that the energy transducer comprises a preselected shape;
- and
- shaping the pole materials such that the pole air bearing surface comprises a trapezoidal shape at the trailing edge.
