A tape head including a body exhibiting a tape-bearing area is provided. The body comprises at least one transducer that is a read element or a write element, configured in the tape head so as for the tape head to read from or write to a magnetic tape, in operation. The tape-bearing area is essentially covered by an electrically conducting layer of material. This way, the exposed surface of the electrically conducting layer essentially forms the tape-bearing surface of the tape head, which surface contacts the magnetic tape, in operation. A tape head apparatus for recording or reproducing multi-track tapes including the tape head is also provided.

A unidirectional and bi-directional tape head with sub-ambient pressure cavities. The tape head is adapted for reading and/or writing to a magnetic tape. The tape head includes: a tape-bearing surface; a transducer area, having at least one transducer designed for reading and/or writing to the magnetic tape; and a cavity open on the tape-bearing surface adjacent to the transducer area that extends parallel to the transducer area and transversally to the longitudinal direction of circulation of the tape such that an opening of the cavity faces the tape in operation. The cavity is further dimensioned and arranged with respect to the transducer area to create, upon circulation of the tape in operation, sub-ambient pressure therein. The present invention allows for a very close tape-head spacing.

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 magnetic element can be constructed by forming a write pole with a tip portion that continuously extends from an air bearing surface (ABS) along a plane orthogonal to the ABS to a body portion that continuously extends from the tip portion distal the ABS. A first write gap layer can then be deposited in contact with the write pole before a processing layer is deposited in contact with the first write gap layer. A magnetic shield may then be formed atop the processing layer with the magnetic shield being separated from the write pole by a first gap distance on the ABS throughout the tip portion and by a second gap distance distal the ABS along the plane orthogonal to the ABS along the body portion. The first and second gap distances can be measured parallel to the ABS with the second gap distance being greater than the first gap distance.

A magnetic write head having trailing magnetic shield and a trailing magnetic return pole that are recessed from the media facing surface. The magnetic write head includes a write pole, a trailing shield that is separated from the write pole by a non-magnetic trailing gap layer and a trailing magnetic return pole that is connected with the trailing magnetic shield. The trailing magnetic return pole and at least a portion of the trailing magnetic shield have surfaces that face the media facing surface. The surface of the trailing magnetic return pole and at least a portion of the surface of the trailing magnetic shield taper away from the media facing surface. This recess prevents far track interference by preventing stray magnetic fields from the trailing magnetic shield and trailing magnetic return pole from inadvertently affecting the magnetic media.

A magnetic write apparatus has a media-facing surface (MFS), a pole, a write gap, a top shield and coil(s). The pole includes a yoke and a pole tip. The pole tip includes a bottom, a top wider than the bottom and first and second sides. The pole tip has a height between the top and the bottom. At least part of the top of the pole tip is convex in a cross-track direction between the first and second sides such that the height at the MFS is larger between the first and second sides than at the first and second sides. The height increases in a yoke direction perpendicular to the MFS. The write gap is adjacent to and conformal with the top of the pole at the MFS and is between part of the top shield and the pole. The top shield is concave at the MFS.

An apparatus has a main pole layer of magnetic material, a second layer of magnetic material, a first gap layer of non-magnetic material between the main pole layer and the second layer of magnetic material, and a second gap layer of non-magnetic material disposed between the main pole layer and the second layer of magnetic material. The second gap layer of non-magnetic material can be directly adjacent to the second layer of magnetic material. In accordance with one embodiment, this allows the gap to serve as a non-magnetic seed for the second layer of magnetic material. A method of manufacturing such a device is also described.
