Heat assisted magnetic recording transducers having a recessed pole

A HAMR write transducer coupled with a laser for providing energy and having an air-bearing surface (ABS) configured to reside in proximity to a media during use, the HAMR transducer comprising:

• a main pole configured to write to a region of the media, the main pole being recessed from the ABS by a first distance, having a beveled surface and an ABS-facing surface adjoining the beveled surface, the beveled surface forming a bevel angle with the ABS, the bevel angle being less than ninety degrees, the first distance being at least fifty nanometers and not more than one hundred fifty nanometers;
• at least one additional pole adjacent to the main pole in a down track direction, the additional pole being recessed from the ABS by a second distance greater than the first distance;
• an interferometric waveguide optically coupled with the laser and having a plurality of arms for directing a portion of the energy toward the ABS at an acute angle from the ABS, a portion of the waveguide having a width and residing between the at least one additional pole and the ABS, the second distance being at least as large as the width;
• at least one coil for energizing the main pole, the at least one coil carrying current in a first direction on a first side of the main pole and in a second direction on a second side of the main pole, the first side being opposite to the second side, the first direction being opposite to the second direction;
• a near-field transducer (NFT), a portion of the NFT residing at the ABS, a first portion of the energy from the laser traveling through the waveguide such that the NFT couples a second portion of the energy from the laser to the media;
• a first pole having a pedestal, a portion of the pedestal residing at the ABS;
• and
• a shield having a shield pedestal, a portion of the shield pedestal residing at the ABS, the main pole residing between the shield and the first pole.

A heat assisted magnetic recording (HAMR) disk drive comprising:

• a media,
• a slider,
• a laser for providing energy;
• and
• a HAMR write transducer coupled with the slider, the HAMR write transducer having air-bearing surface (ABS), a main pole, at least one additional pole, a waveguide and at least one coil, the main pole being configured to write to a region of the media, the main pole being recessed from the ABS by a first distance, the at least one additional pole adjacent to the main pole in a down track direction, the additional pole being recessed from the ABS by a second distance greater than the first distance, the waveguide being optically coupled with the laser and directing a portion of the energy toward the ABS at an acute angle from the ABS, a portion of the waveguide residing between the at least one additional pole and the ABS, the at least one coil for energizing the main pole.

A method for fabricating a heat assisted magnetic recording (HAMR) write transducer coupled with a laser for providing energy and having an air-bearing surface (ABS) configured to reside in proximity to a media during use, the method comprising:

• providing a main pole configured to write to a region of the media, the main pole being recessed from the ABS by a first distance;
• providing at least one additional pole adjacent to the main pole in a down track direction, the additional pole being recessed from the ABS by a second distance greater than the first distance;
• providing a waveguide optically coupled with the laser and directing a portion of the energy toward the ABS at an acute angle from the ABS, a portion of the waveguide residing between the at least one additional pole and the ABS;
• and
• providing at least one coil for energizing the main pole.
