A system, according to one embodiment, includes: a main pole; and a trailing shield. A first distance D1 is defined in a track direction between the trailing shield and a pole tip region of the main pole; and a second distance D2 is defined in the track direction between the trailing shield and a second region of the main pole located behind the pole tip region, where D2 is greater than D1. Other systems, and methods are described in additional embodiments.

A magnetic write apparatus has a media-facing surface (MFS), a pole having leading and trailing surfaces, a trailing shield having a pole-facing surface, a write gap and coil(s). The pole's trailing surface has a portion adjoining the MFS and oriented at a nonzero, acute bevel angle from a direction perpendicular to the MFS. The pole-facing surface includes a first portion adjoining the MFS and oriented at a first angle substantially the same as the bevel angle, a second portion oriented at a second angle greater than the first trailing shield angle, and a third portion oriented at a third angle substantially the same as the first angle. The write gap has first, second and third thicknesses adjacent to the first, second and third portions of the pole-facing surface, respectively. The first thickness is constant. The second thickness varies. The third thickness is constant and greater than the first thickness.

A recording head includes a near-field transducer proximate a media-facing surface. The near-field transducer comprises an aperture portion surrounded by walls of plasmonic material, the walls oriented normal to the media-facing surface. A notch protrudes within the aperture.

A heat assisted magnetic recording (HAMR) write apparatus has a media-facing surface (MFS) and is coupled with a laser that provides energy. The HAMR write apparatus includes a waveguide, a near-field transducer (NFT), a pole and coil(s) for energizing the pole. The waveguide is optically coupled with the laser and directs a first portion of the energy toward the MFS. The NFT is optically coupled with the waveguide. The pole writes to a region of the media and includes a pole tip. A first portion of the pole tip is at the MFS and is separated from the NFT in a down track direction. A second portion of the pole tip is recessed from the MFS and between the first portion and the NFT.

A magnetic head includes a main pole, a write shield and a gap section. The write shield includes a trailing shield, a leading shield and two side shields. The gap section includes a trailing gap section, a leading gap section and two side gap sections. Each of the two side gap sections and the leading gap section increases in thickness with increasing distance from a medium facing surface. In the medium facing surface, the thickness of the leading gap section is greater than the width of each of the two side gap sections, and the width of each of the two side gap sections decreases with decreasing distance to the leading gap section.

A method provides a magnetic transducer having a media-facing surface (MFS). The method includes providing a pole, providing a side gap, providing coil(s) for energizing the pole and providing side shield(s). A portion of the pole resides at the MFS. The side gap is between the pole and the side shield(s). The side shield(s) have a gradient in a saturation magnetization such that the saturation magnetization increases in a yoke direction perpendicular to the MFS. The step of providing the side shield(s) further includes providing a nonmagnetic structure having a side surface parallel to the MFS and providing at least one side shield layer. A portion of the side shield layer(s) are on the side surface. The portion of the side shield layer(s) has the gradient in the saturation magnetization. At least part of the side shield being formed by the portion of the side shield layer(s).

A microwave assisted magnetic head is equipped with a main magnetic pole that generates a recording magnetic field to be applied to a magnetic recording medium from an end surface forming a portion of an air bearing surface opposed to the magnetic recording medium, a trailing shield that is disposed interposing a write gap at a trailing side of the main magnetic pole, and that forms a magnetic path with the main magnetic pole, two side shields that are disposed at both sides of the main magnetic pole in the cross track direction, respectively, and a spin torque oscillator that is disposed within the write gap. The write gap is configured to substantially linearly extend along the cross track direction when viewed from an air bearing surface side, and is positioned between trailing-side end surfaces of the main magnetic pole and the two side shields, and a leading-side end surface of the trailing shield.

The present disclosure generally relates to a magnetic media drive employing a magnetic recording head. The magnetic recording head comprises a first write head, a second write head, at least one read head, and a thermal fly height control element. The first write head is a wide writing write head comprising a first main pole and a first trailing shield. The second write head a narrow writing write head comprising a second main pole, a trailing gap, a second trailing shield, and one or more side shields. The first main pole has a shorter height and a greater width than the second main pole. The second main pole has a curved or U-shaped surface disposed adjacent to the trailing gap. The thermal fly height control element and the at least one read head are aligned with a center axis of the second main pole of the second write head.

A data writer can have at least a write pole separated from a return pole by a non-magnetic lamination. The non-magnetic lamination may consist of first, second, and third non-magnetic materials that are each different and configured to provide a physical protrusion on an air bearing surface of less than 4 Angstroms.
