摘要:
in certain embodiments, an apparatus includes a write pole tip having a top side that has a monotonically decreasing slope that forms a convex profile between a write pole paddle and an air bearing surface.In certain embodiments, an apparatus includes a write pole tip having a first and second top bevel. The first top bevel is at an angle greater than the second top bevel with respect to a plane perpendicular to an air bearing surface of the write pole tip.

A write element including a pole tip shield is disclosed. In embodiments disclosed, for example, the pole tip shield includes side shield portions fabricated of a graded magnetic moment material to form graded side shield portions having a magnetic moment that decreases in the down-track direction along a length of the side shield portions. In another embodiment, the pole tip shield includes side shield portions having a shortened length extending along a partial length of side edges of the pole tip. In illustrated embodiments, the side shield portions are formed of a contoured body having an indented portion forward of the leading edge of the pole tip. The indented portion has a rounded indented surface contour forming a rounded profile for a gap region between a leading edge portion of the pole tip shield forward of the leading edge of the pole tip.
摘要:
A magnetic shield is adjacent a write pole. The write pole has a body portion with a body thickness and an extension portion with parallel first and second sides that each tilt towards the magnetic shield at a predetermined angle proximal to an air bearing surface (ABS). The extension portion may be capable of enhancing a write field gradient of the magnetic shield by reducing magnetic saturation.

A write head, the write head having an air bearing surface, the write head including a magnetic write pole, wherein at the air bearing surface, the write pole has a trailing surface, a leading surface that is opposite the trailing surface, and first and second surfaces; a trailing shield proximate the trailing surface of the magnetic write pole; first and second gaps proximate the first and second surfaces of the magnetic write pole; first and second side shields proximate the first and second gaps, each of the first and second side shields having a trailing shield surface; and first and second antiferromagnetic-coupling layers positioned between the trailing shield surfaces of the first and second side shields and the trailing shield.
摘要:
An apparatus and associated method provides a magnetic element, such as a data transducing head. A first permanent magnet may be configured to bias the write pole to decrease remnant magnetization and erasure after write (EAW). The first permanent magnet can be separated from the write pole be a predetermined distance.

摘要:
A write pole structure includes a write pole having a tip region. A shield structure is spaced from the write pole by a gap at the tip region. The shield structure includes a front shield and a spacer layer on the back of the front shield. A yoke is formed on the write pole, and an end of the yoke is aligned with the back end of the spacer layer.
